Hopefully Street Fighter 2 HD takes a hint and uses sick modern remixes of their music in the game, instead of the original. That would be sweet.
I know they had some remixes planned, although apparently the XBLA size limit is making it difficult to include in the game (along with the regular music, HD graphics, etc.). I think they'll probably find a way around it though. Maybe they can convince MS to up the limit, or just get rid of it completely. Doesn't really make sense to have a limit on this kind of stuff.
