Microsoft has stepped out once again to deny that future Xbox 360 titles will require a hard drive in order to run following increasing concerns from Core owners. It is estimated that there is 2 million core units installed across the world.

Quote:
"Every game will work with every Xbox 360 system," a Microsoft spokesman told GamePro when asked about the "Hard Drive Required" sticker. "But just like some games will require you to have a Memory Unit to save games, some games will require you to have a Hard Drive to experience them."
