BotW2 is in a weird place. I can’t see Nintendo bringing yet another teaser to the hypothetical June Direct, yet it would be surprising to have a full blowout already because of all the other titles due before this one. So do they skip it altogether? If it were E3, I’d say there’s not a chance, but now I’m not so sure.
Personally, I think it would be the right time for a first meaty trailer and title reveal, but probably no Treehouse Live segment nor in-depth gameplay. Then in September or at a dedicated event later this year, after they’re done marketing Xenoblade and Splatoon, they show actual gameplay demos, announce the release date and all that good stuff.
