So about an hour into the game, I've got a team that looks something like this:
Lvl 13 Treecko
Lvl 13 Poocheyena (not gonna be around much longer)
Lvl 6 Tailow
The coolest thing they've added that I see so far: there's a chance a pokemon will spawn in the grass with part of it sticking out and shaking (think like the shaking grass from Black and White.) You can sneak up to them by lightly pushing on the circle pad and they are typically stronger/rarer than usual and can have rare or interesting moves on them.
Example: I caught a Surskit with Fell Stinger on it (for those who don't know, this is an egg move only for Surskit, as far as I can tell)
