There have been reports of the Collectors Edition discs being scratched to all hell because the plastic clips that are supposed to be holding the disc in place don't function properly. Once the disc is dislodged these faulty clips turn into the enemy as the loose disc bounces around and gets gashed....
Someone posted a video yesterday (it's not very easy to tell it's scratched, but considering the widespread reports of this I'm willing to be it's pretty bad):
