Though I am on XBL I do feel a little miffed by some of my purchases. For instance the purchase of XIII gave me the soundtrack, but I lost out when Steam Edition came out with NESTS Kyo, '95 Iori, and Mr. Karate for nothing extra. I feel jipped slightly. Same thing happened when I got SSFIV AE on 360 (good thing I followed my gut and waited). Steam has a package of this game with ALL OF THE EXPENSIVE DLC for $47.99.
