The fact that this calls that one game "Pokken Fighter" makes me think this is very fake. No chance that nintendo would release the game with that title in the West (and it doesn't have a "(temp)" tag). Pretty much the same thing with Project S.T.E.A.M. ...that just screams "codename"
Also, XenoMech? Doesn't really sound too great to me...
However, this is a pretty great line-up and it would be wonderful if it was true
