Recently, however, Street Fighter X Tekken producer Tomoyaki Ayano effectively dashed those hopes. In an interview with Siliconera, Ayano confirmed Mega Man and Pac-Man will forever remain exclusive to the PlayStation 3:
"Ayano: Unfortunately for Xbox 360 users, Mega Man and Pac-Man are exclusive to the PS3 version of the game.
Every game has data on it that is unused. In this case, Street Fighter X Tekken for the Xbox 360 did have the Mega Man and Pac-Man data on it. But, we never intended to release these characters on the 360. They are PS3 exclusives and that was our intention from the very beginning. They are not going to be timed exclusives either, they’re PS3 exclusives."
In other words, 'ol Mega Man and Pac-Man aren't coming to the 360 for no real reason at all.
Color me confused.
