I hear you. I'm a raytracing guy and I look forward to Ryzen and would love to try Naples. But this intermediate thing sounds like a 3rd platform squarely between those. It even has 16 cores rather than 8 or 32, so if the core count doubled or halved it would be very much be competing with one of the other market segments processor.
It seems 16c will be clocked at 3.1-3.6GHz, whereas Naples significantly lower (which is OK for servers). I'd go with 16c for sure for movie rendering (ehm, if only ReelSteady could do a multicore image stabilization rendering...?)
