Super Street Fighter 4 producer Yoshoniri Ono was on a live stream showing off the game. Some readers took screen captures of the stream. We finally, after all this time, have our first image of the character select screen! Also shown is the Main Menu and the Stage Select screen. Keep in mind that these could be placeholders, but it offers clues.

Thanks to TurtleSnatcher, Lost Fragment and Dizzy-4U from Neo-GAF for the screen captures!

TurtleSnatcher even figured out the layout of the characters on the character select screen.
