But really, this will likely be the last generation of consoles to support a physical disk.
I imagine that by the end of this "round" of consoles 60%+ of game sales for these consoles will be digital downloads.
What do use game sales look like in a digital marketplace? If you allow gamers to freely transfer licenses then what is to stop me selling my game to someone in singapore at 1AM when I have finished playing and then coming back the next day and buying the same game back at a reduced rate from someone in australia who has just gone to bed and picking up where I left off?
The only sensible way to allow this would be via DRM which makes /r/gaming shit the bed.
