Literally, not much else came up. There are more videos, although I have included some. The other videos are literally from the screenshots that were posted. The only thing we learned on Day 2 was that the image that is not in XY 3DS style, is from a video, it may or may not be a hint of a WiiU game. Second, we also learned about some additional moves that can be learned. For instance, that Froakie uses Bounce. Serebii has an updated list of each pokemon's known moveset from all of the footage so far. Just check the new pokemon section.
One great thing is that Fennekin is practically 99% confimed psychic. I learns Psybeam and Psychic..I mean, what else could it be, other than the remote, and I mean remote chance of being a fairy type.
Less than two days away from the EURO Gamescom Pokemon XY Demo Coverage!! So we might get some more info. Though, they may be using the same exact demo. Also, more english screenshots might appear.
