Cloud: You don't need a dvd/cd/whatever-burner to put that in application. If you'd read the patent, they say it can be achieved by using a magnet placed in the tray. It doesn't write anything on the disc, it erases.
As for the disc in itself, I give it a good expectancy. It's the system that will get modded to go around it (make it think the game you inserted is already registered and the characteristics are the same).
