Well, the xbox had to get a whole new version of Morrowind to add the expansions as there was no way to add the expansions to the hard drive. As for the "Knights of the Nine" there is an interview on IGN.com where Todd Howard, Executive Producer of Oblivion says that the Xbox 360 and PC versions will be getting "Knights of the Nine" and that there are no plans to release a game of the year version of Oblivion which tells me that Xbox 360 and PC will be getting "Knights of the Nine" as DLC. Which if is indeed the case I'll buy it as I have lots of microsoft points just waiting for more Oblivion content.
