Exactly my thoughts on that. I was kind of scared of pokemon being less cartoony if the graphics when 3D, but now that they're doing it, I just can't get enough.
We might still be seeing sprites in the Pokedex... or not.
Honestly, I kind of wanted to see sprites, but I can always just play the older games. I like the new 3D style. It's cute and reminds me a bit of Colosseum/XD.
Will they still keep double, triple, rotational, battles? I didn't see any footage on them.
Maybe we are not given one in the game; we would have to buy a Pokedex 3D Pro from the eshop. Hey, because it is a 3ds game, we can pause in the middle of a battle and look up.
I'm sure there will be an in-game Pokedex, but not as comprehensive as the Pokedex3D.
Besides, when you switch from a 3DS to a 3DS App or vice versa, you need to close the game. So no. You can't just switch that easily. You will be resetting every time.
I hope that X and Y's battle animations are almost directly ripped from Pokemon Stadium 2. I loved the announcer (doubt he is coming back), the way that battles rotated but most of all, I loved how there was still half of an animation if the move missed. Here's to miss animations!
