If it was real b/c then it might be a big deal, but it isn't. It's a great feature and it will incentivise 360 owners to trade in for Xb one. But if you have a substantial game collection then the only way to guarantee you will always be able to play your 360 games is keeping your 360, and then there is a level playing field for PS4 and Xb one again.
So the main reason MS may get huge sales because of b/c is if there is some misleading advertising by claiming xb one is b/c without being clear about the limitations.
Also, who has been waiting for b/c? Everyone more or less resigned themselves to never having b/c before e3.
