A few moments ago, Major Nelson revealed that there would be an Xbox 1TB name your game bundle. It will be available for people in Canada, France, Germany, Australia and New Zealand.
This is an upgrade to the 500GB name your game bundle, which came with an Xbox and a choice of either Gears of War: Ultimate Edition, Rise of the Tomb Raider, Forza 6 & Rare Replay. The games to choose are unknown yet, but more details will be coming soon. However, if it were the same games, getting Gears of War with it will be a good investment, with the beta coming earlier for the owners of the game.
