Does Microsoft have a new Xbox One game announcement up its sleeve?
Microsoft Studios executive Phil Spencer tweeted late on Sunday evening that it was "personally going to be a good day tomorrow, looking forward to a games announce coming early in the morning."
"Fun part of the job," added Spencer.
Xbox spokesperson Larry "Major Nelson" Hryb added that it "looks like I’ve got a busy morning coming up tomorrow."
In his position at Microsoft, Spencer oversees the development of the company's first-party studios, which include 343 Industries, Lionhead, and Rare.
Microsoft recently announced that it shipped 3.9 million Xbox One consoles worldwide before the end of 2013.
