Honestly I was worried I was too hyped for Pokemon GO, I didn't want to be disappointed by my high expectations. But this game is incredible, I just really hope content comes out regularly enough to keep people interested.
-A Gen VI Pokemon Stadium that allows you to customize your character and battle trainers from all the games. Could be called Pokemon World Tournament (based on the B2W2 thing)
-Pokemon Snap sequel/remake for the Wii U. This would be amazing, especially if it had some sort of connectivity...
Everything is canon now, but in my opinion the main games are:
FireRed and Omega Ruby
HeartGold and Platinum
Black and Black II
Of course, if Z is released that will replace Y, and future Gen I, Gen II, Gen IV and Gen V remakes will replace those games, since ORAS and XY are their own...
What I expect will be announced: Some Super Mystery Dungeon news, maybe something about Pokken, possibly but unlikely some news about Pokemon amiibos (if anything probably just the Mewtwo amiibo), and the most unlikely, Pokemon X2Y2/Z
What I wish was announced: Pokemon Snap U, <Insert Stadium...
Very unlikely. Ideally it would be awesome though. If they did make it, it would be with Wii U HD graphics, otherwise it would take way too much work to do both. Plus it would be its own unique game rather then just all 6 regions on one game.
