Capcom has gone into detail on their blog about their plans to roll out downloadable content for the XBLA version of Street Fighter III.
The first DLC pack will be the “Colours Pack” for $2.99 which is a simple pack that gives you seven new colors for each of the game’s fighters.
The second and third will be “match packs” which will feature loads of footage from competitive Street Fighter III tournaments. Specifically, the recent “Fight for the Future” event. Each of these will pack in over an hour of footage and include commentary as well. The price has yet to be announced.
The final pack will offer character music from the other versions of SFIII. Expect these to be rolled out in the coming weeks and months.
