Microsoft has revealed that its press conference will last for 90 minutes, putting it in line with previous conferences from the company.
We'll likely hear of a new Forza at Microsoft's conference, along with news on Gears of War, Scalebound, Crackdown 3 and backwards compatibility. We're at least expecting the Mass Effect titles to start working with Xbox One.
There may also be news on the new additions to the hardware line up, such as the Xbox One slim.
E3 takes place June 14-16, although the press conferences start on Sunday with Bethesda and EA, followed by Microsoft, Ubisoft, and Sony on Monday.
