We know that the Xbox One will cost $499 and will ship with Kinect as well as one controller. If you want to invite a friend over to play with you, you'll need to buy a second controller separately. Similarly, if you want to chat with friends using a headset, you're going to need to buy the headset separately.
This past weekend, Microsoft finally revealed just how much gamers can expect to fork out for the headset or a spare controller. The Xbox One accessories page currently lists the wireless controller alongside a $59.99 price tag. If you're after the wireless controller with play and charge kit, you can expect to pay an extra $15 ($74.99). The Xbox One chat headset, which Microsoft recently described as a must have (though it's possible to chat via Kinect using the motion sensor's mic), is priced at $25.
The Xbox One is due in November and will cost $499. For that price, customers will get the system, one controller, Kinect and a free 14-day trial for Xbox Live Gold (for new members only). Microsoft will also offer a limited-edition commemorative bundle for those that reserve their units ahead of time. This will guarantee you can get the Xbox One on launch day and will feature "premium" black packaging, a limited edition Xbox One Day One , and a commemorative Day One Achievement. There's also bonus content for those who reserve Ryse: Sons of Rome, Forza 5, Kinect Sports Rivals, or Dead Rising 3.
