I don't believe they were destroyed either. The cost of destroying that many discs would be in the millions, not to mention a rush order to get more reprinted. That just doesn't happen in Q4.
The cost of putting a patch out on PSN is virtually free. Guess which one they did?
There are 2 part numbers for the title though, one was patched on the disc, the other gets patched over PSN.
I doubt it's worth much, the first 50,000 or so units were all unpatched.
