It's a trifecta of Ultimate Marvel vs Capcom 3 updates today, with a new trailer, a patch, and the delay of the latest DLC.
The latest patch has been described as free DLC, as it also includes Heroes and Heralds, a new mode exclusive to the Ultimate version of Marvel vs Capcom 3, in which players can join the heroes or villains of the combined universes. You can collect and equip special Ability cards which enhance character's abilities, and you can take your customised builds into online play to give them a real test.
Shoryuken reports the patch also corrects a number of glitches, from the notorious Reverse World to Vergil's hovering to infinite tech throws. Hit the link for a run down of patched glitches discovered so far.
The next piece of premium DLC, on the other hand, has suffered a delay. Capcom Unity reports the Anicent Warrior costume pack has been pushed back to March 6, in order to remove Magneto's alternate costume - likely due to complaints from the Spanish royal family.
Finally, below you'll find a trailer for the Vita version of the game, which releases alongside the console in February. The trailer takes in Vita-specific functions, namely touch controls; using your Vita as a PS3 controller to utilise the touch controls there; Heroes and Heralds and Spectator modes; online play; replays; content sharing through Near; and DLC sharing with your PlayStation 3.
