Update 2: Our man on the ground Tom Bramwell was able to speak to corporate vice president of Microsoft Phil Harrison about this hot-button issue and was able to confirm that a second user can install a game from a friend's disc for a fee, though it's unclear how much this will be. Harrison also confirmed that several users sharing a console can access the same game at no additional charge, and Microsoft has "a solution" for the resale market, though it's staying mum on those for now.
However, the Twitter outright denys it.
It's one Twitter account versus a lot of journalists now.
