It may not have been meant to be revealed just yet, but Microsoft happened to confirm two new characters in the forthcoming Street Fighter X Tekken.
If you take a look at the product page over at xbox.com, and turn to picture 11 you will see that Heihachi and Dhalsim have been paired with Ling Xiaoyu and M. Bison.
Perhaps, not too much of a surprise, but still... Oops!
