I have not seen a good book yet describing the added value of the new standard and have not had access to read it yet, so just curious what opinions are and if the investment of time is warranted yet.
Actually there are several new components in HEVC that have not been used in any other standard before.
In my opinion, the most important one is the facilities that they have provided for its parallel processing called Wavefront Parallel Processing (WPP).
In addition, the block structures and sizes has underwent major changes.
As far as I know, the scalable version of HEVC has not been standardized yet. So does its 3D version.
I think the best way you can learn about the innovations is to read this paper:

Moreover, there is a very good group in LinkedIn in which many of VCEG members actively participate in discussions. There you can find useful information about its compression efficiency and its possible drawbacks!

Good luck!
Moshen - thank you for the pointers. I will read the paper and pass on to my peers interested in H.265. The parallel processing is interesting - so perhaps more well suited to acceleration with CUDA perhaps on the encoder side? I know some companies (e.g. http://www.elementaltechnologies.com/) have been involved in this type of approach on the head end encoding side.
