During a Super Street Fighter 4 tournament, Street Fighter's Yoshinori Ono and Namco's Katsuhiro Harada gave some details about Street Fighter X Tekkens upcoming DLC. They are 12 character outfits which have Street Fighter characters in Tekken outfits and Tekken characters in Street Fighter outfits.
It's a pretty interesting DLC since some look cool and some are just flat-out hilarious. My favorite is Law dressed up in El Fuerte's costume. Screenshots below.
No details were given when we can get our hands on the DLC.
Street Fighter X Tekken comes out on March 6, 2012 for Playstation 3 and Xbox 360. Oh and if you're getting the PS3 version and wondering when the exclusive PS3 characters are coming, they will be released a week after the game comes out.
