Microsoft's Phil Spencer has promised that the Xbox One will be getting more exclusives in 2014 and hinted that release dates for Halo, Quantum Break and Sunset Overdrive will be announced.
"We will have announces [sic] in 2014, already working on the plan. I want to have a great E3 this year," said Spencer on Twitter, as spotted by OXM.
Spencer also replied to a question regarding release dates for Halo, Quantum Break and Sunset Overdrive, saying, "Most of those will be clear to fans by the end of our E3 briefing."
So it seems that as well as new Xbox One exclusives, we can also expect news of release dates for one or more of Halo, Quantum Break and Sunset Overdrive at E3 2014.
