My most anticipated character is Balrog. I think he has become more popular over time, possibly due to his Daigo's use of him in SF2 and his original popularity in SF4 vanilla (particularly when Justin Wong used him at Evo 2009).
I love that he's based on Mike Tyson and his muscles are insane!
Also, there are so many great poses.
He's going to make an amazing statue.
(plus his alt costume could be the america flag boxing gown)
