The Neuron VS comes with the same sound engine as the hardware Neuron keyboard and, together with <Nuke>, the hardware controller box, Hartmann claims to have put a resynthesis system in the hands of the musician, that offers exactly the same sonic features as the hardware Neuron synth.
The Neuron VS has an MSRP of US$999/EU€706 (or at least it did when it was announced) and can be ordered from their online shop or from your local dealer.
NOTE: Their online shop doesn't appear to have an entry for it, so you can't actually buy it from there yet!
