I'm a fan of physical media for many reasons, but the primary one will always be that if I own a console and a disc-based game, nothing can take my power to play that game away from me, short of destruction/theft. Digital is all well and good, but it is quite unsettling thinking about the fact that I can't protect my digital ownership nearly as well as I can my physical things. That stuff can be taken away from us outright, or we can suffer the effects of some sort of internet catastrophe, and all of a sudden we lose everything we don't currently have downloaded.
Bleh! I'll always prefer physically owning my things.
