Ooh, but how soon is very soon? Today soon? Tommorow soon? Next week soon?

I'm excited!

Oh please tell me new Pokemon, that's really the most exciting part for me..

Ooh, looking forward to it!

Always nice to get more info. Just 4 more months, just 4 more months...
Hoping for more Grass-Types (as usual). Chespin and Gogoat are awesome, I really hope to see more awesome designs.

I am really glad with the amount of information that is being released about X and Y!

Okay it's already been revealed to France and Japan but not here in America.

It's a Steel/Ghost Sword Pokemon 



Old school pokemon fans are gonna have a field day with this one 

A Steel/Ghost sword Pokémon? That's interesting.
Design-wise, I'm not that huge a fan, so I do hope that it evolves into something a little more cool-looking. But I do have to give mad props to Nintendo; I hadn't expected a Steel/Ghost sword. Love the typing, now we have another unique type combination done.

Also, from the looks of it, it kind of levitates. Maybe it'll have Levitate, and could this mean that this Pokémon will be the next Bronzong and only be weak to Fire!? :O

Pokémon! You know what happens when you collide with the Monster Hunter universe!

Joking aside, I hope Chespin's evolutions will be Dark/Grass. We need something less butt-ugly than Shiftree.
