New Alolan forms would be nice, yeah. Or heck, even straight-up new Pokemon, however unlikely that is. Wouldn't mind new Megas either Actually we'd probably sooner get new Z-Moves, huh?
Anyway, looking forward to more info, as well. Part of me wants to give Ultra Sun a chance, but part of me wants to save my money... I guess it doesn't help I only got Sun two months ago, so maybe I'm just not in a hurry to try it either way.
The apparent "alternate telling" thing is a pretty cool angle imo, but I hope they go the whole hog with it instead of "Mostly the same as the first two versions but with minor differences/bells & whistles" like pretty much every third version ever. Not that more post-game would be a bad thing; as much as I personally liked the Battle Royal, even that gets old after a while.
