If you haven't already checked, make sure to pop Street Fighter IV into your console and get that free update from Capcom.  It's been up on Xbox LIVE Marketplace for the weekend and a few days on PSN.

The "Power Up Pack" adds new Championship Mode adds tournament features like double-blind charact selection, a detailed Replay Mode, and a ranking system.  The whole package will cost you 16 MB of your HDD, which is considerably bigger than the paid Resident Evil 5 "Versus" DLC, at just 1.8 MB.

16 MB is a hell of a lot less suspicious, at least, so there will probably be considerably less fan-rage over this.  And hey, at least it's free this time -- if that's any consolation.
