I remember reading back in late 2008 that there was going to be a release of Ghostbusters the first film on USB format. I looked today for it and no one talks about it, and I don't see it at amazon. What Happened?

This definitley did happen as my friend had a couple. They were sold in the UK at a computer games store and also in the argos catalogue store apparently.

I can't really help any more than that, all I can do is confirm it was available in the UK for sure.
