This is STREET FIGHTER x TEKKEN
It's slated for a release in March 2012 (according to wikipedia lol).
Apparently theres going to be a TEKKEN X STREETFIGHTER, which uses the Tekken battling system, as Streetfighter x Tekken uses the Street Fighter 4 system.
Anyway, as I've revealed before I really like collecting pictures....and I've found the artworks for the featuring characters. Needless to say they are very cool!
