Those who attended Nintendo's Japanese 3DS event have discovered that in Super Street Fighter IV's 3D mode, the camera adjusts to a view where it simply rests on the characters' shoulder.
"It's like a different game," said a 4gamer reporter. (translated by Andriasang)
All other commands operate normally and the camera is plastered on the character's back at all times. To see this for yourself Tokyo TV offers some decent footage.
