Here is the GURPS page describing the new GPD, for those that are interested and haven't seen it yet:

The only change I know of is that I believe it is now a 176 page book instead of the listed 160 pages. According to ADB's website (the publisher) the final manuscript has just now been sent to Steve Jackson himself for final approval, and assuming he doesn't want any major rewrites it should go to print shortly thereafter.
Here is the link to the publisher's discussion board topic on GPD, where they have been posting regular schedule updates on how it is coming along:
