Default Backwards compatibility with DVD and CD

I'm confused as to why the PS4 won't play CDs. As I understand it, the ability to play audio CDs is required by the DVD spec. In other words, if the hardware has the DVD logo on it, it has to play CDs. Likewise, I thought the Blu-ray Disc spec requires playback of DVD, (and thus CDs, as well). What's the deal?

It has nothing to do with the hardware, it's the software that's missing, but will be added later at some point, it won't play mp3 either.

AFAIK backwards compatibility is not required by either BD or DVD specs. Most BD (and DVD) players are backwards-compatible, of course, because BD & DVD each adopted the CD's physical format (5"/120mm optical discs); only laser wavelengths, disc formats and software differ. Still, the BD logo alone does not guarantee DVD playback, nor does the DVD logo alone guarantee CD playback. (Indeed, BD & DVD players aren't even required to read all discs of their own formats; most DVD-Audio discs aren't readable by most DVD players, and reportedly the Xbox One won't read recordable BDs.)
BD players: PS3 Slim 250GB; Sherwood BDP-5004 (region-free); HP P7-1010 w/ LG WH12LS38K, AMD HD 6570, TMT 3, 5 & 6, PDVD 11, Nero 11
A/V hardware: Vizio E3D320VX 3DTV; Sony HT-SS380; Vizio Co-Star (Google TV); Radiient HDMI switch (PC also has Hanns-G HL227 & Altec Lansing 2.1 speakers)

It's false outrage, I don't know anybody who bought a launch day PS4 and rushed home so he could play his audio CDs on it. Nobody cares, especially not the younger demographic who buy consoles.

Im sure they will add it in later and 99% of owners will continue not playing audio CDs on their console.

I understand the desire for the end all be all ultimate it plays it all machine, but I don't understand the desire to throw all past tech out when new comes into play, not saying the OP did, but all the negativity to not be the ultimate machine... its sad. But if everyone complaining is chucking their old tech, lets have those addresses. I'm sure some people would appreciate a vintage piece of gaming history like the PS3/Xbox360 or an ancient 3D Blu-ray player.

Not hating, I just don't mind having a few pieces of equipment on my entertainment center.

yup, it does not cost much to add but it is not required by the formats.

agree, not because I want a lot of junk but because at the end of the day if an other tool is better for the job I would use that and , at least in my experience, a multi-tool is always better. I also don't get this outrage even more since Sony said they will add all that crap, but they were busy focusing on gaming until now. So what is the big deal with using what ever you are using now for A/V until it is added. I bought a PS4 to play next generation games that are running at 1080p.
