Like with BB and UMvC it's a perfect port in every regard with graphics slightly dumbed down to keep it the 60fps standard expected of the fighting genre. The game will only be as good as it originally was on console even with the Vita specific content meaning it will be in the 80s on Metacritic but won't outdo Rayman Origins. I honestly see SFxT Vita selling better due to it coming with every piece of DLC and unlocking that DLC onto your PS3 copy of the game free of charge, whereas consoles already have MK Komplete with all DLC for as low as $30.
