What titles have you found out there that use this type of encoding? Must do some testing.

Anime stuff, for example by m33w-fansubs, Doki Fansubs or Coalgirls who released some files. Check out their homepages to find them.
The Hi10 files are playing on a normal media player/XBMC, but since they're not properly supported yet, there are a lot of artifacts.

10-bit h264 decoding support was merged into FFmpeg on April 14 and into libav on May 12. So whichever of the two projects they decide to base their player on, this functionality should be available in the next XBMC release.
However, I hope this isn't a trend in video encoding because it's incompatible with DXVA / VAAPI / VDPAU playback.

Slightly off topic:
I was intrigued, so I tried to read about this online, but couldn't find any technical explanation for why it offers better quality for a given bitrate (for animated clips)
Anyone have a link?

Is there any more word on support for this in the future. It appears that more players are starting to pick this up and it looks like fan sub groups will begin to make full releases in it starting in the fall. In addition some groups are already redoing all BluRay content in 10-bit.
I can also say that for those of us that want to digitize our blurays for easy playback the new 10-bit encoding offers a way to dramatically reduce file size while improving quality.

I have been doing some reading on hi10p since these anime distributors are all running towards it head on, not caring how anyone else feels on the situation.
The one thing I am really wondering about, is it even possible to have hardware acceleration of 10-bit encodes on future codecs with current hardware? I am just thinking of all of these people with HTPCs built from laptops, netbooks, and ion based boards being SOL.
I do see a huge benefit for 10-bit encoding, moreso for us who backup our movies onto NAS boxes for their network. Allowing more movies with the same space, saving the need to buy more hard drives and saving money in the long run.
As I said, these encoders dont really care about anyone else though. One comment I came across was "thats what you people get for buying such devices" referring to someone using a WD box.

Some of them are fairly pigheaded about it *cough* Commie *cough*, but others such as Doki actually bothered to ask what their supporters thought. The thing to keep in mind is that no one is forcing anything on you, you have the option of simply not downloading their releases. Most shows are oversubbed anyway (done by multiple groups) or can be watched shortly after release on streaming sites like ANN and CR. None the less the stubbornness of a few encoders has made this issue way more overblown than it needs to be, hint those are the ones saying things like "DURRR JUST USE TEH NEW CODEC PACK", just try and keep in mind they are the exception and not the rule thus far. It's going to be a rough transition no matter what, but throwing accusations back and forth isn't going to benefit anyone.

That is exactly why I was searching around about the hardware support in the issue, if it could even be done. If it was purely a codec support issue then it wouldnt really be a big deal as in time it would be solved, much like XBMC using DXVA on Windows. But considering its the hardware lacking it becomes a much larger problem. Not just because it would take a little time for chip makers to add the features, but they would have to see a real benefit in even taking their time to do so before they even thought about implementing it. And as jwcalla said, they wont bother until displays are up to the challenge. And I dont see that happening anytime soon, not until broadcasters start moving to 10-bit.
A plus to all of this is that it is already in ffmpeg and will be in the next XBMC, so you WILL be able to view hi10p videos. Just make sure your next XBMC machine has a CPU capable of doing so... One thing this has taught me is my next box will most likely be a pretty decent CPU, if anything just to be a fallback when GPU acceleration fails.
