why are we assuming the next 2d zelda has to take place in the current iteration of hyrule? we've seen these games jump around the timeline a lot even on the same platform, the next game could totally take place at a different point
they could easily outsource a new 2d game to another studio and it'd be a great way to fill in the gaps during the 5+ year wait b/w the big 3d zelda's, if anything they have all the reason to keep making original 2d games
