Today marks the beginning of Capcoms annual Captivate event. They revealed a bunch of Street Fighter info.
Basically...
$15 DLC or $40 for the Disc Release.
The DLC drops June 7th. The retail disc will be out June 28th.
PC version drops in July.
Sounds like you won't actually be able to pick which version of the character you want to play with, but moreso picking whether you want to enter SSF4 matchmaking or AE matchmaking.
too much info released today to put into my own words. so i'm just going to copy/paste the rest.

"The meat of the update are the four new characters: Evil Ryu, Oni, Yin, and Yang. Each bring their own unique fighting styles and move sets to the fight, along with fully animated intro and ending videos. If you'd rather rely on your old favorites, Capcom is promising entirely new alternate costumes, as well. The balance of the roster has also been tweaked across the board, putting it in line with some of the known balancing changes in the latest arcade iteration of the fighter.
Capcom isn't settling with simply dumping new characters and costumes into the game, though, and has also focused on building up the online portion of the game, in particular in the area of replays. The "Elite Channel" will only feature replays from the top tier players, those who've accumulated 3000 PP or more; no more getting stuck watching scrubs weakly fighting one another. If you want to get even more specific, you'll be able to search for and follow specific Gamertags and online IDS, as well. The sharing functionality of the replay system is also being tweaked, making it even easier to share multiple files with your friends and rivals.
The "Endless Battle" online mode has now been expanded for Arcade Edition. Called "Enhanced Endless Battle," this mode will allow you to set even more specific conditions for matchmaking, allowing online fighters to fine-tune the battle experience. Players will also be able to get more information about their opponent while in a match, too; the HUD will now not only display the opponents online ID, but also their PP and their BP.
Capcom is also addressing concerns over splintering the Street Fighter IV community with a new, paid update. An update will be coming to the current Super Street Fighter IV that will allow those players to play matchmaking games with those playing Arcade Edition. While players who don't upgrade to Arcade Edition obviously won't have the new online features and new characters, they'll still be able to play online without any trouble even if they decide not to update."
