Update:

Xbox's Major Nelson has officially unveiled the new Xbox One 1TB console after it was inadvertently leaked by Amazon last week. He confirmed the new controller design featuring a 3.5 mm headset jack and said that the Left and Right Bumpers have been adjusted for better press-detection. Xbox One controllers can now update wirelessly without having to directly connect to the console.

Original Story:

One of Microsoft's big E3 2015 reveals may have been leaked a little early in the form of a 1TB Xbox One system with a revamped controller.

Polygon reports that a special $400 Xbox One was listed by Amazon. While we should expect bundles, price drops and all kinds of new announcements going into E3 month, we're surprised Amazon let something like that slip. This new Xbox One system features 1TB of storage space, a copy of Halo: The Master Chief Collection as well as a redesigned controller. This controller features a 3.5 mm headphone jack, which will let you plug in your own earbuds or headphones for use during gameplay. Previously, you needed to buy a special adapter to plug into your Xbox One controller in order to fit a 3.5 mm-based accessory. While Amazon was quick to take the listing down, Wario64 caught all the details (featured below).

Here is the item's Amazon description:

There's only one place to play the best exclusives and biggest blockbusters this year, like Halo 5: Guardians, Rise of the Tomb Raider, and Forza Motorsport 6. Experience the most advanced multiplayer on Xbox Live, powered by hundreds of thousands of servers that maximize performance while reducing lag and cheating. And quickly switch back-and-forth between games, live TV, and apps. Now includes a 1 TB hard drive for storing games and media, a controller with a 3.5 mm headset jack, and Halo: The Master Chief Collection, the definitive Halo experience on Xbox One. Play through The Master Chief's entire story with Halo Combat Evolved: Anniversary, newly remastered Halo 2: Anniversary, Halo 3, and Halo 4.

We'll probably get an official word (and an offhand, awkward joke) about the new console once Phil Spencer hits the Xbox stage at E3 this month.
