Having purchased DimPro, Rapture, Zeta2 and various add-ons separately, and being a Producer level ProAudio/Sonar/SPlat consumer, I also am very interested to see what is new in this hybrid. I, too, own ZebraHZ and the late, great Alchemy, among others.
I have no issues purchasing new software if it is good. Of course, there is always a risk the software may be offered at a discount or bundled free in the future. Cakewalk has done this with all of their synths; U-He never does. Different business strokes for different business folks. Both offer discounts for early adoption.
It's a question of paying for the latest competitive edge. A hybrid of DimPro/Rapture/ seems redundant to me, and the EDM spin is not enough to pry open my wallet. Perhaps some raw patches and synth process descriptors would be more intriguing. Sampling, Granular, Wavetable, FM, Additive, Subtractive, Monkeylazers, tin can and strings....???
