Pssst, official word from Paramount by way of the *Iron Man* thread and the digital bitz:
"The official word on the Iron Man BD is in from Paramount. The discs that will be available on street date at your local retailers WILL be fixed and working fine, so no worries. We're also told that because the discs will be corrected by street, there will be no need for any kind of exchange program. Just so you know."
