In "my console is better than yours" news, the Xbox 360 will need to use two discs to handle all of the military meatiness that is Battlefield 3. The PlayStation 3 will require only one Blu-ray disc. This comes from a picture that is incredibly Japanese, but I'm willing to trust things I read on the internet.
In other news, PlayStation 3 owners are just a little fatter than Xbox 360 owners. Experts* believe this is due to the fact that PS3 gamers don't have to get off their couches as much as Xbox 360 players.
