Microsoft has more Xbox One exclusives to announce in 2014, Xbox executive Phil Spencer teased on Twitter recently. Responding to a fan, Spencer said he has high hopes for Microsoft's E3 2014 media briefing in June 2012.
"We will have announces in 2014, already working on the plan. I want to have a great E3 this year," Spencer said to a fan who asked about the Xbox One's software lineup for 2014.
The Microsoft-owned Black Tusk Studios is working on multiple unannounced projects for Xbox platforms, while it was just recently confirmed that Fable developer Lionhead Studios is working on an all-new IP as well.
Regarding Xbox One games that have been announced--like the new Halo game, Quantum Break, and Sunset Overdrive--Spencer said fans should expect to learn release dates for "most" of these games by the end of E3 2014.
