The folks at ign sat down with ono san today during the first day of the tokyo game show and talked about Street Fighter IV in general.
During their talk, Ono san confirmed that dlc will be on the pipeline as well as different gameplay modes, unfortunately he also confirmed that bonus stages will not be included in the home version due to time constraints.
From the article: "Ono said it won't be just arcade and versus, but whatever is eventually included is still being worked on and therefore he didn't want to say anything. Bonus stages, such as barrel or car smashing, won't be in the game, however, as Ono says there isn't enough time to get it in there and Capcom would rather get the game out than delay it to add bonus modes. "
While i would really love to see the bonus stages done in sf4 style, i would rather have the game sooner with no bonus stages rather than months later with the bonus stage.
