We’ve been following it for awhile, but here is solid proof of an Arcade Edition of Super Street Fighter IV being on the way. Consoletech has an exclusive trailer leaked to them from an anonymousness source, revealing Arcade Edition to be downloadable content for Super Street Fighter IV.
According to the trailer, this update will add quite a bit of new content. Most importantly, four new characters, Oni, Evil Ryu, Yun and Yang will all be jumping into the brawl. All character balancing made to the arcade release will also be present in the console release. You can switch between playing SSFIV players and Arcade Edition players.
New features include a revamped replay mode where you can post your replays and share them online. People can, what looks like, subscribe to your video account, seeing replays as you save them. They will also be adding an Elite Channel, with replays of players with 3000+ PP.
