There are Blu-rays that had transfers mastered at 4K resolution, but current Blu-ray specs cannot fully capture 4K resolution. Sony has released a number of 4K-mastered BDs in a special line.

There is a true 4K format for home viewing, though it is download-only on a proprietary server. Only a handful of people in the United States have it.

The Blu-Ray Disc Association expects to announce the final specs for true UHD Blu-Ray discs by the end of this year, with players and discs expected to be available by the fall/winter of 2015. Early reports indicate that the new players will be backwards-compatible with HD Blu-Ray discs, but DVD will not be supported.

I've been looking for detailed specs and haven't been able to find them. Do you have any links?

Dropping DVD surprises me. Does the new format require a new laser? If it also reads existing Blu-ray discs then we are still talking about 2-laser systems, right?

Any hints about the security regime? At one time there were speculations about per-disc watermarking and a required network link to phone home and check keys.

I also don't understand why they'd necessarily need new hardware if it's still the same blu ray laser in both the HD and UHD variants. Seems like a waste to force everyone who already has an HD Blu Ray player to spend more money and upgrade to UHD Blu Ray rather than trying to make it work on existing hardware.

If new compression codecs are used, could be the existing players don't have the processing oomph to handle them.

That would be crazy if they don't support it. Would it need more than the current number of lasers in current players to support it (would UHD discs need an extra laser)? Wouldn't that mean people would be less likely to buy them, since they'd then need two players if they also wanted to play DVDs.

I was watching a series of CES 2014 interviews when I came across the comments regarding the expected lack of compatibility with DVD discs. I'm not sure if there's a valid technical reason for it, though I seem to recall that CDs and DVDs require a ruby laser and BDs use a blue laser. There are currently no consumer Blu-Ray players that can read the double-sided, triple-layer-per side discs being tested for UHD by Sony and Panasonic. And manufacturers have plenty of incentive to come out with new hardware: Back on April 10, 2003 Sony came out with the BDZ-S77, a $3,800 recorder that was only available in Japan---at the time, it was the first and only consumer Blu-Ray player in the world. With UHD Blu-Ray they'll get to start the cycle all over again.

The BDA hasn't made any recent announcements on the topic, but I found these articles during my search:
