Howard Shore was recently here on Reddit. Currently, it looks like he's remastering the score to King Kong while he works on other projects.
Most of The Hobbit scores appear to have been published in two-disc editions, however.
According to Shore:
I guess we'll see in time. It took quite a few years to prepare the complete recordings of LOTR - Fellowship took a year, Two Towers took a year, and Return a year, so it was a total of 3 years of preparation for those releases - so I have to now go into the archives and see what we haven't released at this point in the two-disc editions for each of the films.
Remembering that in LOTR, there was only one CD disc released initially on each of the 3 films!
Hope that helps!
