The Xbox One! It looks terrific, assuming you're into turning your home entertainment system into a motion-and-voice-controlled dictatorship. And while the devices won't be shipping until the "end of the year" (read: in time for the holidays), you can go ahead and preorder yours right now.
You've got two preorder options, according to Xbox guru Larry Hryb (better known as Major Nelson): You can go to Amazon or the Microsoft Store online. Going with the latter will get you a $10 store credit, while it's doesn't seem that Amazon is offering the same incentive.
Have at it! And yes, just to be clear, this is the preorder for the preorder. [Twitter]
