Prove it! I suppose if you just got lucky it could happen...but I seriously doubt that strategy would keep you going for long time and time again.
OT, but those movies actually sold pretty well for some reason, which is why most movie studios started putting out movies on UMD (originally, it was just Sony Pictures). I think they may have slowed down recently though, or at least the sales of the Spongebob Squarepants UMD didn't do as well as the studios expected.
I thought I heard somewhere that the PS3 might have a UMD port. Have you heard anything about that RC?
No, at least not recently. A long, LONG time ago, there was a fake PS3 case shown online that had a UMD port. That's the only time I heard that.
