You are speculating, the historical evidence is that 1) they shutdown the halo 2 servers even when there was people still playing the game 2) they stopped supporting xbox as soon as xbox 360 come out 3) they will completaly drop backward compatibility with xbox 360 on xbone, 4) For now countries outside the 21 announce will not be able to play xbone games regardless if there are xbox 360 games on those country.
This is in relation to gaming but is the same with their software, for example, MS stopped support for windows xp to force users to migrate to windows 7 even though windows xp has 54% of the market. So what historical evindence states is that is more likely that MS will have you place all your games under their DRM schema and when next next gen comes they will shutdown all server and not provide backwards copatibility to force you to move on to the next next XBox.
