Street Fighter X Tekken 2013 trailer explains it all

Having said a new version of the crossover brawler was on the way, here's a new video from Capcom showing off some of the new features. The 2013 upgrade adds faster fighting, recoverable damage and more to improve the pummelling experience. Again, never seen an official notice about this being for Vita, but since it is more or less the console version, it should make it over.
