Here's some confirmed info from some guy at Capcom:
* Super Street Fighter 4 is tentatively set for a spring 2010 release (Xbox 360 and PS3).
* The update will be released on a disc, and won't be available as DLC (Downloadable Content) — but the game will be priced as an upgrade — not a brand new title.
* As this time, they're thinking of adding about 8 characters to the game. (Rumors currently have this pegged at 10 fighters total).
* Capcom is planning on adding more features to the online modes. Things so people can enjoy playing as a group. (Sounds like lobbies are in).
* There will be tweaks and balance changes, along with more online stuff and new features the developers are adding in.
* Bonus Stages aren't 100% confirmed, but it sounds very likely they'll be making it into Super Street Fighter 4.
* You won't need the original disc to play this update, but fans who have a copy of SF4 will be, "happy to have held on to it," as they'll be receiving something nifty.
* Juri is a Korean Tae Kwan Do fighter and is very important to the storyline.
* They skipped "Champion Edition" and "Turbo" and jumped straight to "Super" for the name of this upgrade because of the scale and size of what they're planning.
Those characters are apparantly meant to be (but it's not confirmed): Dee Jay, T. Hawk, Dudley, Ibuki, Makoto, Adon, Cody, Guy, Juri and Hakan. We definitely know that two of them are Juri and T. Hawk, and
maybe Dee Jay.
