Console exclusives have always been important, and will continue to be important to Microsoft, says Xbox boss Phil Spencer.
"Exclusive games will continue to play a major role for Xbox in the new console generation, just as they have in previous generations," he said. "This E3 is important for us to show gamers our future plans for exclusives and third-party support."
"Right now I think we have a strong lineup of in-development exclusives, including games like Sunset Overdrive, Project Spark, Quantum Break, and Halo, in addition to some exciting titles you will hear more about at E3," he said.
"It's going to be great at E3 to be able to share the games coming exclusively to Xbox One, and it's only going to get better."
E3 2014 takes place June 10-12 in Los Angeles.
