Microsoft's E3 press conference will last a full 90 minutes, kicking off at 5.30pm UK time on June 15.
Xbox chief Phil Spencer confirmed the conference's length on Twitter, while also adding that they are currently tweaking the presentation to fit everything in.
Apparently the conference will have "in-depth looks at previously-announced games" and trailers for "unannounced titles coming in 2015 and beyond."
Rumoured announcements include the likes of a new game from Rare and the Gears of War remaster. Rise of the tomb Raider, Halo 5: Guardians and Forza Motorsport 6 will be shown during the event and we'll probably hear more on Crackdown and Scalebound too.
