However, not every street fighter fan owns a playstation or a PC gaming. Some of them are Xbox players.
I do participate in a XBox gamers group, and there is a guy that was hugely disappointed by these news, cause he is a strong Street Fighter fan as he is a Xbox fan.
And we will never know how much truth there is in that "fact" that SFV would take more 2 or 3 years to be done without sony I guess... and even if that was true, coming for every platform is always the best option if you're trully thinking on the gamers. Actually, if that was the case Sony could just have done a temporary exclusive contract, of 1 year or 2, that would already be enough for them to market the hell out of the PS4 for fighter gamers, and still would allow the game to be multiplatform, as it should have been.
