The issue isn't profiling the 11 inks, that's straightforward. Support for the iPF5000 and the HP Z series will appear when the next generation of Imageprint is ready, which is what is taking them more time than they had anticipated.
I spoke with Colorbytes a couple of weeks ago and they said then that they hoped to have it ready before the new year. We'll, they've got another week, but don't hold your breath.
I expect to get a review copy just as soon as it's ready, and will announce here when it arrives and my testing starts.
