Next-Gen Ultra HD Blu-Ray Discs Probably Won't Be Cracked For A While (arstechnica.co.uk)
DVDFab, a software tool for ripping and decrypting DVDs and Blu-ray discs, will not be upgraded to support newer Ultra HD (4K) Blu-ray discs. Fengtao Software, which makes DVDFab, said in a statement that it "will not decrypt or circumvent AACS 2.0 in the days to come. This is in accordance with AACS-LA, (which has not made public the specifications for AACS 2.0), the Blu-ray Disc Association and the movie studios." AACS-LA is the body that develops and licenses the Blu-ray DRM system. AACS 2.0 has a 'basic' version that sounds quite similar to existing AACS, but also an 'enhanced' version of DRM that requires the playback device to download the decryption key from the internet. There might still be a hole in the AACS 2.0 crypto scheme that allows for UHD discs to be ripped, but presumably it'll be a lot tougher that its predecessors.
Some notes from someone in the industry...
The 'enhanced' version is not yet used, everything out so far is using the basic AACS2, it is unknown exactly when the enhanced will be available for use. Knowing how past AACS requirements have never materialized, I actually wouldn't be surprised if this never really takes off. Also Fox is really the only studio I know of that is interested in this. They are also the only one I can think of that uses BD+ regularly, and are more technically minded than other studios.
Streaming is no where near the quality of these discs. Someone posted that Netflix streams 4k at about 16Mbps, while the video on these discs will be over 100. Also the bigger aspect of video on the UHD discs is bt.2020 HDR color space, which I don't think Netflix does yet. M-go is the only place I know of that has similar quality video, Fox tries to use the same encode on the UHD BD as they do for their "Vidity" downloads on there. Also if sound is important to you, I don't think anyone streams Dolby Atmos or DTS:X audios.
