MS knew that it had to stop the defection of 360 owners jumping to PS4. How do you convince people to stay with you? Make sure they can play their last gen games and new gen games on one machine. If I have a 360 and I'm looking at a new gen machine b/c makes me look seriously at Xb one especially when I can get a very good trade in deal. I can get a cheap Xb one because I can now trade in my 360, AND get to keep playing my 360 games. Also if I have a PS4 and a 360 then I can seriously consider getting that second 8th gen console earlier than I might have.
The one problem is that this isn't true b/c, therefore you are not guaranteed to be able to play all of your 360 games. But still if you like the mainstream Xbox franchises you will be pretty safe.
It was a smart move to shore up the base, but it's not going to attract new customers.
