On gameplay innovation: honestly, I'm fine with the core gameplay being the same, because every generation, they inroduce new moves, new Abilities, and polish and rebalance he ones that exist.
They also make training viable teams a hell of a lot easier. It was never easier to breed and train up a team than it was in Black and White 2. Get the right nature every time using an Everstone, EV train by feeding your Pokemon cakes and giving them haircuts, and send them to the dojo for about 10 free levels a day.
But what I really like is seeing new attacks, and new Abilities, and seeing how they all interact with the stuff that came before. It's like Magic he Gathering, really. At its core, it has the same gameplay formula it's had since 1990, but there are so many new tricks and powers that interact with each other in new ways that saying it hasn't innovated or expanded is like judging a flowering cherry tree for its roots, because they haven't grown out much this year.
As to the starters, I'mm interested in the fire fox whose name I still can't remember. I'm not worreid that it'll be a retread of Ninetales, because c'mon. There are so many magical foxes in mythology (not just Japanese myth, either) other than the nine-tailed kitsune. maybe it'll resemble the trickser Renard. Or a tube fox.
Looking at the trailer, we see two moves from each starter. I like to imagine this could be a hint towards their ultimae typing. The fox does Flamethrower, and then some move with purple waves. That could either be a weird animation for Growl, or perhaps Confusion or something. The frog does Water Gun, then some quick roughing-up move in close quarters. Possibly Quick Attack? Probably not Fury Swipes, bu maybe even Close Combat. And the hat thing has Solarbeam, and something that could be resonably argued to either be Aerial Ace, or Pursuit.
