You could also say that more than half of XBox One owners have never tried an excellent free feature. Is that because of simple disinterest or is half the user base new to XBox and never owned a 360.
Once I get a Scorpio, of course I'm going to try out a few of my old 360 games. Same as I downloaded the ps3 games that got free ps4 updates. Not that I played them long, just long enough to satisfy that nostalgia itch. Although PGR 3 and 4 might get some more attention.
Another stat I'm more interested in is how many people actually watch 4K blu-ray on XBox One S, how many times has the app been downloaded and how much use does it get. Any 4K blu-ray sales numbers in general would be great. Is that format going anywhere...
