I think I'm going to have a Talonflame on my in-game team. If its stats will be good even on my battle team as well. Well, it will be one of the pokémon at least. I had over 20 level 100 battle pokémon in my White version.
Also, Vivillon is pretty cute, though it might not learn Fly, not really sure if any of those first bug pokémon, like Butterfree, could learn Fly.
Noivern could be also a possibility, you would also get a Dragon type in your team. Would be useful against the new Fairy type.
Do we know if any of the previous generations' pokémon will be available to catch when going through the game? Like, not only these new pokémon will be available. I got kinda lost in the video game news for the last 2-3 months. :<
