I don't know. I expect NDSP would get the biggest bang for the buck with a new hardware SKU whose OS were as similar to the QC's as possible. Preferably, the very same codebase/ deliverable, auto-detecting which platform it's running on and enabling/ disabling features accordingly.
Eliminating the ability to create new captures makes sense, if that's what you mean - if for no other reason, because it allows them to remove some I/O, preamplification, and ADC/DAC hardware, reducing cost and footprint. But I don't see any reason for any of the capital-M Models and effects to be omitted; and the screen and UI should be very similar if not the same. Plug-in compatibility (S O O N) should also be present - it's a potential revenue draw for no additional R&D cost.
That's the way I'd do it... who knows what NSDP will arrive/ has arrived at after crunching numbers on cost vs. "what the market will bear". (Acknowledging that someone present in this very thread already knows exactly what they've done LOL.)
