..Blu Ray support? The PS4 doesn't play Blu Rays?
Sorry for my confusing wording. I meant a remote for blu-ray playback, like the one I use on my PS3. I often see it referred to as a blu-ray remote in other forums. It's of course technically a bluetooth remote.
Most formats require a license cost, CD audio playback included. That's why it will probably not be added, the ROI isn't there.
I disagree that that's the main reason. Licensing fees didn't stop Sony from enabling my $80 smart blu-ray player I bought the same year as the PS4 came out to play CDs. Nor does it stop manufacturers of $25 DVD players to allow CD playback. As yourbeliefs mentioned, you would still expect an optical disc drive to play one of the most ubiquitous and low-tech incarnations of disc media.
I think it was more to do with Sony not wanting to put time and money into developing an app that would allow the PS4 to do some of the things the PS3 did with CDs, including ripping CDs, downloading/saving disc info from the Internet, organizing ripped media, creating playlists, and the various playback functions (repeat, shuffle, etc.). There are also of course the various paid subscription music services Sony has been pushing.
I personally would be happy if I could simply put a disc in, see an generic CD icon appear in my navigation menu, and hit play.
