It'l probably come out in the U.S., too...but that might be a while.
(Also, I'm sensing a pattern here...First Smash Bros, now Pokemon. I can only imagine what else Namco Bandai would help contribute to Nintendo...Fire Emblem crossover with Soul Calibur mechanics, maybe?)
Some other thoughts: Well, Lucario and Machamp are in this, and Blaziken was in that teaser shot from last year...chances are, most of the Pokemon are at least part-fighting type. I wonder what other Pokemon would be in this? I'm gonna guess...Mienshaou, Breloom, Pangoro, Hitmonchan, Hitmonlee, Hitmontop, Toxicroak, Hariyama, Gallade, Sawk, Throw, Hawlucha, Heracross, Medicham, Infernape, Scrafty, Primeape, Poliwrath, Emboar, Gurdurr, Chesnaught, MAYBE Cobalion, Virizion, Terrakion, Keldeo and, if it's not limited to fighting types, possibly Lopunny (mega evolution) and Zoroark (actually, I just wanna see Lucario and Zoroark duke it out...Hey, I can dream.)
