Appearntly Microsoft's supply is extremely limited atm with some stores only being able to take 16 xbox one pre-orders and 60 PS4's

If you are planning on pre-ordering an xbox one you may still do so on Amazon or Gamestop.com but the stores themself will no longer take your pre-order Intil microsoft ups the supply (there are rumors of production issues involving malfunctions)
