Should we call X1's backwards compatibility Cross Buy Lite?

Maybe cross buy is "Cross buy lite" because only a few of my PlayStation games actually worked on other PS systems. Meanwhile, I'm part of the XB1 preview and I already have like ten 360 games that work on my XB1!

Out of interest, do you need the disc for them all?

I'm wondering if they will sell the games on XBL store as well, to make extra money of course.

Not if you bought then digitally.  A couple were GWG games.  A few were XBL Arcade games.
