It has been confirmed that the starters Chespin, Fennekin, and Froakie will be pure Grass, Fire, and Water types.
So there goes the speculation of Fennekin being Fire/Psychic and Chespin being Grass/Dark. Personally, I think their evolution lines will have these types at some point. But that's just a thought, it's not confirmed in any way.
The names of the new Legendary Pokemon were revealed today! Unknown Legendary X is Xerneas (ZURR-nee-us), and Unknown Legendary Y is Yveltal (ee-VELL-tall). I know, the names are weird now, but like previous generations, I'm sure we'll get used to it.
It has also been confirmed that there will now be OVER 700 POKEMON. (obviously, I mean, it's a new generation. Each generation releases at least 100, with the set number being about 150.) I was a Master...now I need to catch ANOTHER 150! O.o

(Like in a building, a forest, a desert, etc.) This wasn't seen in the trailer, but I noticed differ
