YouTube user SoulReaperTTG has managed to get a hold of all the introductions for the 12 PS Vita-only characters in Street Fighter X Tekken which releases for PS3 and Xbox 360 next week. That above is Blanka and Sakura's. The rest are available through the link below.
The prologues have no narration, just moving art. In addition to Blanka and Sakura, they cover Guy, Cody, Dudley, Elena, Alisa, Lars, Jack, Bryan, Lei and Christie.
These characters are, so far, announced only for the Vita version. The Vita version is due for release later this year. Yet if someone has their hands on the videos now, three days before the console game's release, what the hell does that mean?
They're probably console DLC, is what, and the big stink will be if this stuff is actually already on the disc. A commenter at EventHubs, which aggregated these videos, says it is (how else would we be seeing this video?) along with the Pac-Man and Mega Man characters releasing a week after launch.
