Bump.
I think mechanically, we might be similar overhaul to BotW. Nintendo is going to find a simple set of mechanics that make the game what it is (like shooting, rolling, and scanning) and milk each of them to the maximum potential that they can be fun. This might mean some things get chopped, we see some new things, or some things might be totally revamped to be less like keys for locks and more like tools for puzzles (maybe Grapple Beam or Missiles).
Also, hopefully the lighting won't be godawful and I'll be able to see where things are.
