I agree that there will still be some that have physical disk drives until we make the leap from disc based medium to fully digital, like VHS to DVD. Countless amounts of people like myself still use their playstation as their dvd/bluray player. I have to throw in there are tons of people who don't even have basic internet access, let alone to means to purchase new games, relying on used physical copies. But, the big players in the gaming industry might just push out that crowd anyways as they try to force all digital versions on the consumers.
