Um, yeah Tekken x SF is pretty much never going to happen. With the failure of SF x Tekken and Harada saying he had hoped fans forgot about the announcement, it sure isn't looking good.
you remember that weird ass video they had a while back? about like ryu being a cab driver or some shit? it had a hint in it about something being a playstation exclusive. this wouldn't surprise me based on this.
but then again ... remember sf4 was never going to come out on pc according to capcom. and look where it is now, right there on pc. capcom lies right to your face so you can't take anything they say as gospel.
I thought Capcom said the PC release was a delayed release, to help piracy in Chinese bootleg arcades. The SF4 cabs were super expensive and you had to buy them in pairs, so they wanted to cash in on that and avoid the PC version being installed on a PC and put in a cab.
This being PS4 only is pretty much Capcom saying "well, we don't want a bunch of money." It is beyond stupid. Although, I do believe the TE2 works with both PS3 and PS4, so at least, I won't have to buy another stick (although, I probably will eventually).
