Yes in time they can and probably will go away unless consumers visibly and strongly fight it. The gaming industry doesn't want to have the new and used market like cars do. They want to control it all, and they want to control how and when you access it and for the price only they dictate. The stumbling block right now is infrastructure they can't control, the internet. With games into the gigabytes in size these days wimpy 10/100mbit connections take too damn long for the majority of average and casual consumers to put up with downloads like that. My brother works for a third party that has serviced games to all three of the hardware makers and it's an active thing game developers want to have happen and at least two of the three hardware makers are totally fine with it too (ie: not Nintendo) which has been well covered in the shitstorm over the One and their obtrusive DRM and no used games they got shamed out of. Going forward if the internet of the US got to the gigabit level in general for the majority of the populated areas that buy their goods, they'd look into making hardware that don't have disc drives, they'd be boxes like the Ouya you download everything to, but could access through a USB or card to drop stuff on there potentially too. In turn with the death of used games and sharing, they'd lower the price of games because they'd no longer have to print discs, boxes, sleeves, paperwork, deal with shipping boxes, packing materials, and the people and logistics involved. Games could come down to 1/2 the price they are now, but again you lose all your rights, it would be a long term digital rental world where you won't be playing your favorites 20 years later unless they're re-sold and re-emulated to you on a newer box if it's picked up again.
