Depends how big they decide to go? They can still go for a decently sized overworld (50% the size of BotW?) to keep the ope world nature they want to keep, but this should trim development times a bit? They also basically spent the last year of development making sure ultra hand wasn't going to be game breaking as well, didn't they? So a small amount of the team could have already moved on to the next game? I doubt the entire team was just trying to break ultra hand for the best part of a year
Still think this could be one of the few games, alongside MP4 that will be enhanced on the Switch 2, they know the next mainline Zelda game will be Christmas 2026 at the very earliest, more likely mid to late 2027.
Can't believe how quick the last year has gone, might load this up to have a run around Hyrule, sky dive and stay well clear of the depths.
