"Kaz Hirai then took the stage to announce that of course there will be a PS3 hardware bundle containing the game. He didn't mention any details -- no price nor release date, though it's sure to be day-and-date with the standalone software. When Square Enix does show it off, it'll be hard not to hear about it."
