The ink set is based on the HP Vivid Photo ink which is in the Z3200, so should perform about the same otherwise.
Quality info is based on the details we checked with our HP rep and from our manager attending the HP convention a few weeks ago regarding new models and any updates coming soon.
Hope this info helps!

Thank you for the information on sizes of the printers and the head reliability.
The HP Designjets Z3200/Z3100 use Vivera pigment inks since 2006. The Vivid pigment inks were introduced in 2010 with the Designjet Z6200. There is a modification in the Vivid inks compared to the Vivera that improves the gloss and the scratch resistance. The Z6200 had Chromatic Red, Photo Black, Matte Black, Light Grey, C,LC,M,LM, Y, inks aboard. New Vivid inks made for the Z9+ are Chromatic Blue, Chromatic Green and the not yet available GO gloss optimizer. The Z9+ does not use both Magenta, Cyan inks but just one of each and we do not know in what strength actually.
The GO I hope will create a better scratch resistance too, maybe even have properties comparable with a protection varnish. The last is my speculation but any engineer would try to achieve that. With the HP Latex inks in mind it should not be impossible either. Maybe that optional GO channel uses the technology to create that, preheating the ink somewhat before it goes into the head to create the right rheology.
Sure I added some speculation too here but the available facts on the inks are better presented than your information does. And any modification in ink, paper, printer technology alters longevity numbers. For better or worse, we both do not know to what degree. However I share your confidence in HP technology so I sure am not pessimistic that it will all be alright. Even if fade resistance is compromised a bit in favor of scratch resistance I would find that a sensible step in the development of inks for this market.
