Microsoft has discounted the 500 GB Xbox One, as well as its bundles, for its Summer Sale, saying that the discount is available "while supplies last."
Any of these bundles is a part of this discount. This includes the special edition Quantum Break bundle (which includes a white console), and the Name Your Game Bundle, which allows you to pick from Forza Motorsport 6, Rise of the Tomb Raider, Gears of War: Ultimate Edition, or Rare Replay.
For any people on the edge, now just may be the time to take the plunge and join the current generation.
