The folks at the PS Vita Hub have some very intriguing photos.
Tekken Tag Tournament 2 (TTT2) is scheduled to be released for the PS3 in 2012, but these images may reveal that a PS Vita version is in the works as well.
Street Fighter x Tekken will be available for the PS Vita on March 6, 2012 along with the Xbox 360 and PS3 versions.
While the game is being developed by Capcom, it could still be a sign of things to come from Namco Bandai on Sony's upcoming handheld if the rumors are correct.
See the second image of what could be TTT2 for the PS Vita below.
