The console comes with one controller in the box, of course. However, you'll have to pony up the dough if you want additional controllers, as Xbox 360 controllers will not work with Xbox One. At least we quite enjoyed our hands-on time with the next-gen controller.
As with Xbox 360, Xbox One controllers will use AA batteries. However, Microsoft will sell a separate Play and Charge Kit for gamers that want an integrated rechargeable solution. It costs $24.99--$5 more than the current-gen version.
The Xbox One headset has also been priced. It will be available for $24.99 and won't be included in the box due to Kinect's built-in microphones.
