If people could play the same games or their PS2's and Xbox 1s as they can in the current generation, pay 1/3rd to 1/2 the cost of the disk for the exact same game I doubt that more than half the people here would have next generation systems!
Im not motivated to pay 3x more for a disc when I tend to prefer using digital media on a HDD anyway. Personally I don't care enough to pay extra for it, even with the player. If/When the disc prices come down I would consider it, but definately not now.
Tease.
