Personal opinion obviously, but i think its amazing that a machine that is trying to broaden the market, casual, core, media device, shown best media capabilities so far, more actual outright exclusives so far, compelling options with licencing especially digital, seems to come out looking like its in a lot of trouble by the internet.
Yes most games need the net, that's actually why i think the 24 hr check in isn't necessary, which is the only thing i think they really missed stepped with. People will be going online anyway, sell it as compelling reasons to be on line.
That way you get all the benefits of drm, with little of the downsides from ms point of view.
If offline, play with disk in. Its going to be hard to get the most out of most games next gen without being online.
