Nobody said they're not going to be in the game,
just not in the base 16 unless the NA PR dude has no clue or is lying.
I've said before Capcom Cup would be the place to reveal Alex and Urien, talking to
@Sotherius and others, it's just that a direct statement from a branch of Capcom says it's not happening, which I don't know why I need to say this again but that is all I'm stating, I'm not saying they aren't in, base 16 or otherwise, I'm saying the guy who represents Capcom for NA who has been giving info all this time said they weren't.
And Karin was clearly going to be revealed at TGS, this has been said countless times in the thread. As for Mika's reveal, it's was a "surprise", but I don't see why that means it should have been held. There is no reason Capcom Cup can't be new characters, or maybe they think Guile or whoever would really excite people, I can't say.
If Alex and Urien are in the base 16, which would be great, yeah, Capcom Cup is the place.
