[quote name='uberChilders']Hm...well I got the PS3 version of Oblivion GOTY Edition, and all DLC and the main game were on one disc, I don't know if it varies from system to system. However, if it is like Oblivion it should work. Good Luck![/QUOTE]PS3 has plenty of room on the disc to add in the GOTY content with the game info. 360 doesn't, which is why it was on two discs.
As I'm guessing they'd do the same thing this time around, the PS3 version should be on one disc and the 360 version would be on two.
