There’s been rumors that the new Xbox console has an always online requirement, and Francis is not happy about it. Recently games like Diablo III and Sim City were required to be online at all times to play. The problem is, the games launched and players were unable to even get to play the games at all. The problem was so big with Sim City, Amazon had to stop selling the game entirely.
PS4 has already confirmed you can play offline, so it seems that Xbox is willing to do things the hard way.
