@belegorm: No, most tournaments use 360 due to the PS3 version having lag on most stages besides the training stage due to VSync issues and overheating issues. EVO used PS3 because one year Sony was a sponser and they needed them for Tekken 5, so they played it on there since they had them lying around; even they switched to 360 for this year.
Yes and in the last Gen the 360 had the better hardware graphically making the PS3 lag in comparison with their wtf cell chip that no one knows how to program for. Yet we are now in the XB1 and PS4 era, where the PS4 has the better hardware. So going by the same logic, the whole exclusive to the better hardware console isn't a bad thing.
