Street Fighter X Tekken Gameplay vid: Ryu Vs Kazuya

A week ago we saw the Trailer for SxT, announced at the Street Fighter panel at Comicon. Finally, some gameplay of Street Fighter Vs Tekken has finally been released at and it features a really cool battle between Ryu and Kazuya, with special  (super) moves and guest beatings from Chun-Li and Nina.
See video below

Fans were really exited about the Marvel Vs Capcom style super combos, where to Ryu's aid, Chun-Li jumps in to do a super kick combo. While Kazuya is backed up by Nina for some reason, who jumps in to kick Ryu's ass. This game looks like it will have some pretty amazing battles.
