Condensed list of information from Serebii from the Coro Coro reveal:

- Xerneas is pure Fairy with the ability Fairy Aura, which powers up Fairy-type moves, and has a special move called Geo Control
- Pancham has an evolution called Koronda (Fighting/Dark), with the ability Iron Fist, the move Hammer Arm, and a new method of evolution
- Squids called Maika and and Karamanero, Dark/Psychic types both
- Maika has a Dark-type move called Turn Over, which reverses stat changes
- Fairy-type cotton candy Pokemon called Peroppafu, has the ability Sweet Pale, which prevents allies from falling asleep, and has the move Drain Kiss; exclusive to X
- Fairty-type pink bird called Shushup, has the ability Healer and the move Aromatherapy; exclusive to Y
- Honedge has No Guard
- Clauncher is exclusive to X
- Skrelp is exclusive to Y
- The professor in the game apparently battles you occasionally
- The evil team is called Team Flair/Flare
I guess that wasn't as "condensed" as I was aiming for but whatever. There's also two new gym leaders, but you kind of have to see the pictures for that to be very notable.
I'm disappointed that Xerneas is pure Fairy, but then, I've liked Yveltal better from the beginning anyway so I'm not too upset.
Pancham's evolution is indeed pretty awesome. The duo have a very Teddiursa/Ursaring dynamic about them. Although I guess Teddiursa was more innocent and cute.
The squid evolution looks really weird to me, but I am intrigued by the typing. I dunno, it's possible it'll grow on me aesthetically too.
I don't really care for either of these new Fairy-types announced, though I'd have to see evolutions before I fully make that judgment. The bird I think has potential, the cotton candy one...not so much, IMO, heh. I like both Skrelp and Clauncher, though, so it's too bad they're exclusives to different versions.
I'm confused about the team; why is it spelled both ways? I guess they do look like they could have either name, but...they kind of have to pick one, don't they? They look less ridiculous than Galactic and Plasma both, though, so this might be a cool team.
