I'm just observing, and not judging, the fact that this trailer is clearly not attempting to appeal to people who aren't onboard already. While there may well be elements that are new, from an outsiders perspective the view is very much "yes, that's certainly some Splatoon right there". It's a contrast with the Salmon Run trailer, which was very overtly strange and intentionally atmospheric in an eye catching way that is different from the (still very good and stylish) standard Splatoon vibe of this trailer. Again, I am just observing that, not saying this trailer ought to be different than it is.
