It just seems as if Dave does not want a little-bit-of-everything type of company. The whole DSI line is closely related, and I would expect that it's deliberate. Even the Prophet 12 and Prophet 6 bear enough resemblance. Dave's approach/philosophy is the cause, and I would expect to see this continue. But I will not be surprised if that VS-PEK instrument does actually appear.
As for a sampling synthesizer, wouldn't that be a drastic turn?
Depends on how it is implemented I'd say... if you think of a sampler like with the older E-MU Emulator series, then yes... certainly, but exactly what you are mentioning is what I think it could be... something that is a resemblance of things he already have at hand... Dave is using the same tricks as many other bigger companies now; he reuse his code and ideers in new products, enhancing on them... so yes, that is a typical thing of Dave's "evolving instruments" so to speak...
So what I see possible is a growing on something already there... like the P12 for example, but with the added option of using sample oscillators.... I'm not talking about something with a huge multisample-setup engine and loads of voices... that is why I call it a "sampling synthesizer"... most samplers are better for studio use, but what I could see Dave do, is make the sampling synthesizer more suitable for live performance (which seems to be his goal with all his creations lately).
If he created a really good sample oscillator playback routine, that would allow samples to be stretched all over the keyboard without the need for multisamples, just like in the Roland V-Synth machines, the need for multisample setups could also be completely removed...
I can only talk for myself of course, but what I would want of a sampler, is not to recreate realistic acoustic instruments by using multisamples, but rather the advantage of using sampled textures as oscillators, because it does allow for some REALLY FAST creation of huge pads for Ambient music (and other genres), without the need to sit and tweak on normal oscillators for hours on end.... you could simply just choose a sample texture, and start molding that with filters, other sample oscillators ... maybe even with audio rate modulation in the Mod Matrix... I mean... such a way of using samples would be extremely cool for my usage, and I think others would find it useful too.
Put in the V-Synth COSM effect for sideband filters, and you can turn almost ANY sample into a lush PAD sound...
I really hope for such a synth... and if I have not seen anything before I've saved up enough, I'll probably go for a V-Synth GT instead, simply to get a sample synthesizer.... just really would like to see something like that with VCF and VCA
