It looks like an official announcement is coming soon as trailers of Super Street Fighter IV Arcade Edition coming to the console as a DLC is popping out in Youtube although Capcom has been fast in taking them down. ConsoleTECH have managed to get their hands on a trailer from an anonymous source.
Just like the arcade edition, the DLC will have all the goodness such as the four new characters (including Evil Ryu and Oni) as well as various balance changes. The replay channel will get an improvements that allow the player replay data to friends, follow and watch other players’ replays. An Elite Channel is also added for players with a PP of 3,000 and above.
No dates or prices mentioned but we should be seeing an announcement pretty soon.
