Gonna do a trailer analysis
-Trailer starts off with Shez fighting Byleth, I imagine this is at the very beginning of the game, though curiously Byleth does not have the sword of the creator. This means that most likely this timeline involves Byleth never joining Gareg Mach at all, which is what might lead to the war happening/peaking earlier
-Some nice ass music, seems like a remix of Chasing Daybreak
-Nice to see that Shez isn't a silent protagonist, also good design, though I think the purple is a bit too bright.
-Shez seems to use dark element stuff from his weapons and seems to have some sort of goal that requires strength outside of just wanting money. My guess is you will get offers to be hired from whoever saves you from Byleth at the beginning of the game(Claude's line about meeting in a forest corroborates this)
-Crimson Flower is now Crimson Blaze, love Hubert's evil laugh and his attacks look really cool
-DEDUE, looks like he is starting by Dimitri's side right away this time without him being captured. My guess is this means that Cornelia never took over the Kingdom and Dimitri probably discovered she was a spy for the Empire. Glad to see him back, and he is rocking the new braids and beard, only good facial hair in Fodlan
-Hilda, love her new bun hair style. Also the meeting Shez in a forest line is again, probably how the lord of your choosing hires you for their side
-We see what looks like a dragon razing the ground, most likely Rhea, and we also see dark magic circles on the ground attacking church soldiers. My guess is that the Slitherers get more directly involved in the conflict earlier this time and are potentially fighting the Church here. Flayn looks to be a neutral party if I had to guess
-Looks like you can move around the map from your location and that there will be multiple different battles available to you at the same time with different rewards/level recommendations. Wonder if that means you can do certain story battles a little out of order if you risk doing it a bit underleveled or if its just side content that you can tackle in any order
- Edelgard's new weapon is called LABRAUNDA and Shez's class is called FLUEGEL(funny name)/ My guess based on the color scheme is Labraunda is similar to the Arrow of Indra, a Slitherer weapon that matches the power of a relic.
-There is Co-op play(you can see P2 joining as an option next to Shez. Also there are exclamation points by certain weapons/movement types, maybe what is recommended for the level or for Shez? In this case Axe and Tomes are 2 points, Bow and Fist and Flying are one. Foot movement is 3.
Again though, not sure what this could mean
-Looks like you can assign certain combat arts/spells to different button commands and use them as special moves, wonder if everyone can customize to this extent or if Shez just has a ton of options since they can class change. Combat arts do still cost durability in this game and they all have cooldowns, I'm sure both of those get lower with higher level abilities
-The combat arts also show you the area of effect they cover(Wrath strike is just an Aoe around you while Blizzard attacks in a three pronged formation in front of you
-Battalions can be assigned and seem to give some passive bonuses. Empire duelists seem to grant an advantage tier over axes(my guess is that advantage tiers are represented by the exclamation points) and give you 45 percent resistance to axe damage at level 2. Empire Warriors due the same on the axe side and give you lance resistance/bonus damage
-The map they show is a standard seize the strongholds. Looks like Bernadetta as a playable archer in the bottom right portion of the map potentially
-You can give commands do units you are not controlling to move somewhere, to heal or you can assign them as an adjutant, which they show off more a bit later. You can also do something called all out defense. My guess is that this is a class skill for Armored lord(Edelgard keeps the same Post time skip starting class here)
-PLAYABLE MONICA. She seems to be a mage here, maybe this is her not being Kronyafied somehow(maybe because Byleth was not at Gareg Mach?) She uses a weapon called Wind Caller's Genesis(cool name)
-Looks like by assigning an adjutant they will assist on some attacks, they will guard you from damage occasionally, and you can do combined specials with them. Seems pretty useful, but I imagine its at the cost of losing a unit on the map.
-Looks like you explore a base camp instead of the monastery in the game, nice for a change of scenery.
-I like the new training animation, I imagine you can level up characters and weapon/batallion/combat art ranks through training, as well as get support points
-You can also work towards changing classes! It seems to be Shez exclusive, but its nice that you can customize the MC in this game compared to the last FEW
-You see Lorenz doing some managment work in the base camp! Love his new hair more than his normal post time skip hair tbh. Mercedes also looks amazing(as always) and you can see that mealtime is back with Shez eating with Dimitri and Mercedes
-Claude's line is "this world cries out for change while you keep it shackled to the past". This could refer to numerous characters, my guess is Rhea right now but I am not sure. \
-Also we see what looks to be a new relative of Claude's! Maybe a new half brother from Almyra?
-We see Dimitri swat away some dark magic like nothing lmao, we also see a hand reaching out to Dimitri while he mentions avenging those who have fallen. My guess is it could be Rodrigue, since Dimitri is super close with him. But a more out there prediction is in this timeline, maybe, Glenn survived? Either way it definitely involves his past and its supposed to be a secret since the bonus characters in other routes were revealed by face, but they kept this one hidden. CURIOUS
-We see Shez lending dimitri his shoulder, presumable after he is injured in some big battle. We also see what looks to be like Dimitri and Edelgard fighting together!!!? She attacks someone else and is positioned in front of him, so it might be a relatively late game scene.
- We see a bunch of different character scenes with no real significance for a bit, but it looks like Shez is being called a missing cog for Edelgard that pushed her to act, maybe a better influence on her than Byleth who was absent from the Monastery which caused a much more positive turn for Fodlan since she is a bit more reasonable and willing to work with others?
-WE SEE HOLST, he seems to be fighting Lord Bergleiz(Caspar's Dad). Great designs for them both and hopefully they will be playable
-We hear a totally new voice say they're the closes ally we have, my guess is that its the white haired new god that is with Shez on the cover.
-We see side by side shots for all of the new lords alongside Shez, presumably from some point on their route(before the convergence)
-We finally see a clear shot of the white haired god who calls us their partner in destiny, very curious to see where they fit in, my guess is something to do with Agarthans
-Also some Byleth hype as a bit emotionless enemy, we can still pick their gender at the start of the game before we encounter them I imagine
