Project xCloud is getting exclusive games. Microsoft's Corporate VP Kareem Choudry confirmed as much in an interview with Stevivor at X019.

In terms of [Project xCloud] exclusives, we’re in early talks with first- and third- parties, but we don’t have any announcements to share. New content and IP takes eighteen months to two years to develop.
