With the flurry of Super news out of CES, this got overlooked. It was posted on Friday by Anoop on andriasang.
According to a blog post at Famitsu.com made by producer Yoshinori Ono, Super Street Fighter 4 is nearing completion and, using a flight analogy, is on final approach.
He states that he expects the game to make its expected Spring release. Furthermore, he even expects to be able to set a final release date soon!
