It seems like the developer of Warframe was pleased by Microsoft's change on indie developers with self-publishing, so they decided to potentially release Warframe for the Xbox One. Obviously, it was originally meant as an exclusive for the PS4, but that might not be true anymore. I have played Warframe for a few minutes on the PC, but really didn't think much of the game. I'm sure there are some big fans out there that will love the change though.
