Being a Gundam fan and absolutely no games come to the US any longer, region free is another plus for me. Pair that with the great looking line up of launch and launch window games I'm sold.
Capcom announced Ultimate MvC 3 DLC tied to your PSN account will work on both the PS3 and Vita. It's good that the DLC will work multiplatform, but guess what(and this isn't about the Vita?) More pre release Capcom DLC. Bet it's already done and will be released after the games release.
