Capcom has said Ultimate Marvel vs Capcom 3 on PS3 will share connectivity with Vita, allowing you to use the handheld as a controller for the TV version.
The firm refers to this functionality as "Ultimate Controller." Pretty nifty.
Also, the Vita version will allow for match playback, show the button presses you made, and surround your characters with hit boxes. Players can also upload their fight videos, as well download fights posted by others.
The game's manual will be released digitally, meaning the package will be devoid of paper instructions.
Capcom plans to release a free DLC update for the PS3 version of the game on December 19, called Heroes and Heralds.
