Xbox officially announced the disc to digital program

[G2ThaUNiT]

It's arguably the best case scenario in coming to an all-digital future. Digital licenses operating the same way as a physical game would ironically encourages players to keep their physical libraries rather than selling/trading them. I read a reply that if you let your friend borrow your physical game, the digital license goes with them. When they return the disc to you, the digital licenses are returned to you.

Great to see that Play Anywhere support is included with this program.
