Well,
I wish you good luck. I have been waiting for a new version since two years
I have the impression that this project is dead, since I have been seeing the same version for two years and apparantly there is no feedback from the developper on the forum either.
Maybe legal issues of the developper with Adobe ?
However I haven't been able to run gimpshop since mac OS X 10.4 Tiger.
It is a wonder that the website is still alive and that the forum is still up. Maybe there is still some kind of hope after all.
