EVO stream revealed this. Weren't there supposed to be 5 characters added total?

Apparently the fifth is suppose to be a new character thats never been in a Street Fighter game before.

Im calling it now, it's gonna be Asura from Asura's Wrath. The DLC had him fighting Ryu, Evil Ryu, Akuma and Oni. He even gave Evil Ryu that hole in his chest(according to the DLC). Also, Ryu's ending in SFXTekken has him being teleported to Asura's Wrath. Chun Li even makes an appearance in Asura's Wrath's ending. It seems like Capcom has been planning on this for a long time now, slowly inserting Asura into the SF mythos.

I think you're both right.

Calling it further: If it's not Asura, it's a completely new character that's not tied to any existing franchise.

^ I doubt it. It seemed as Combofiend chose those words very carefully when he said "has never been in a SF before". At first I thought it would be Haggar, finally having the Zangief Vs Haggar fight that everybody has wanted. But all of the signs point to Asura as my final answer.

Remember Me chick!
