Exclusive XBOX One and PC Games Most Likely Coming to PS4
This is a list of games that may be coming to PS4, but currently there's no official statement. Many of these games are going to be timed console exclusives on Xbox One. You'll notice that many of these use phrasing such as "first to console" or "console debut" which implies that the game is a timed console exclusive.
