I'm not worried because I don't believe MS or Sony will drop the used game ban bomb. The tech might be in place, but there is no way they will push the button for a long white. Maybe several years into the next gen we might see some games with always on connections, but I just don't see it happening any time soon.
Even if it does happen and even though I hate ownership right infringement, it would take more than that to keep me away from Halo 5.
