And on a sidenote, Barrera also confirmed that cheat codes will indeed be available to use in-game:
It's really no surprise to anybody that the PS3 was definitely a contributing factor to that. Now, we're neck and neck. That's not an issue anymore. But back then that was something we were taking into account. That's not to say there's anything wrong with the PS3 version. It's awesome. They're both identical.
"For gamers who only want to cause havoc, the game will offer that and the standard amount of weapon-unlock cheat codes."
Thanks to Jordan for the heads up.
