There are reasons for Microsoft to not do this, of course. They merely need to see the disastrous launch of EA's always-online SimCity and decide whether the negative backlash of selling people a product that can't work when the servers go down is worth it--especially if the earlier version of that product didn't require that kind of Internet connection.

They could also look at the competition and imagine a consumer standing at a store, deciding whether to buy a PS4 or the next Xbox. One wouldn't require online; the other, if our best sources are right, would. Surely, some would prefer the system without the online requirement.

As mentioned above, things can change. Microsoft may reveal its next Xbox this month, in May or, at the latest, at E3 in June. We'll know more then. We'll hopefully know what they've decided.

I don't see how the document you presented nor the article from Jan 2012 debunks this. Again I don't think Microsoft with go through with this. But this, the Edge article and whatever else does mean something at this point
