That's Street Fighter IV producer Yoshinori Ono holding a new Street Fighter IV publicity poster. Quite swanky! (But it does remind me of the GTAIV "IV" — that's because there are only so many ways to do "IV", I guess.) There's another post after the jump. Same basic layout, but different characters in the "IV" and sporting a different color. Kinda like it better, but you go on and judge for yourself.
Ono seems to like it better, too. Just look at how happy he is!
