The IGNcube story doesn\'t mention exclusivity for the NGC, then again, it also doesn\'t exclude the possibility. The article is mainly saying, "Hey, we know this is going to be announced at Spaceworld," so who knows what else will be announced then. I wouldn\'t imagine it would be using Sony hardware in the arcade and at least not be on the PS2 at some point -- then again Soul Calibur used Sony hardware in the arcade too.
