Microsoft's big news for the 2015 edition of the Electronic Entertainment Expo may have been revealed by Amazon, which on Friday published a product listing for a new $400 Xbox One bundle that will include 1 terabyte of hard drive storage and a new controller for the console that includes a 3.5 mm headset jack.

The listing was quickly taken down by the online retailer and is no longer viewable online, but before it was removed, the listing said the new bundle will go on sale June 15, according to the Verge. That's the same day Microsoft is scheduled to hold its keynote at E3, the video gaming conference where companies typically reveal their biggest news of the year.  

The Xbox One is currently available with 500 gigabytes of storage, so the new bundle will give gamers twice as much storage space for saving their game files. However, this won't be the first time Microsoft offers the Xbox One with 1 TB of storage. Previously, the company sold a 1 TB version of the console as part of a limited-edition "Call of Duty" bundle.  

As for the new controller, gamers will be happy to see that a headset jack will come included. With the console's current controller, Xbox One users are forced to buy a separate headset adapter to connect their headphones.

Besides the extra storage space and new headset jack, the bundle will also include "Halo: The Master Chief Collection," which includes the games "Halo Combat Evolved: Anniversary," "Halo 2: Anniversary," "Halo 3" and "Halo 4."
