Depends. What can you PS4 do? Do you have to pay to make it a plex client? Chromecast to? Can you run vlc on it? Can it transcode? Can you run an opensource game on it? Run a decent browser on it? Steam? How about the collection of Classic Atari games? I've only have public knowledge of the Atari, but X86, cheap, and linux does open some rather interesting possibilities. I've yet to see a media player that does it better than Roku. If the Atari could be the roku of gaming it could be quite interesting, even if it doesn't have the latest/greatest $50-$100 game that the PS4 of Xbox has.
