re5 dlc not so huge, already on disc?

Rumors are flying on the internet that the Resident Evil 5 downloadable content, which adds achievements, objects and new online modes to the game on the 360 and PS3, may have been packaged with the game all along, despite Capcom's claims that it was beyond their development scope for the initial launch. The downloads are suspiciously tiny (1.8 MB on the 360 and only 351 KB on the PS3), indicating that it's just a key that unlocks content already on the game disc. Sooo, it's a little bunk to be charged $5 for this content after paying $60 for the game. Still, I'm sure it's going to sell like hotcakes, with the popularity of the game and of online multiplayer modes in general.
