I wonder if we get a Gold/Silver meets Black2/White2 kind of game. A sort of mid-gen. I mean the roster of new Pokémon we got was small, we randomly got a new Eevee evolution. We still have not got any 3rd game information.
I would love to start in a neighbourhood 'region' and have an adventure there with a story that climaxes with a Zygarde tie-in.
It would also be nice, maybe they could introduce a handful of pre-evo's and evolutions for" old" pokemon aswell, aswell as a fair share of new ones. It already ws suspicious that we got no proper regional trio this era, like the regi's or the birds. And the postgame also was lackluster and short.
