^^^Agreed. People have forgotten about Refills now thanks to these rack extensions as well.
^^^I've had Reason since 3.0. I own The Studio Combo(Piano, Elec Bass, Abbey Keys, Drums) and Electromechanical refills. I don't need a B3 Emulation Rack Extension, I don't need Radical Keys(Electric Piano)or Radical Piano, I have more than enough of all that stuff.
What is still lacking in Reason is a realistic set of guitar patches...stuff like Realstrat or some of those Kontakt expansion libraries that could easily be converted to NNXT libraries.
I got a Garritan Orchestra and Miroslav Refill collection. I'm good on symphony sounds(unless they actually get something like VSL or Eastwest's newer stuff that I doubt the NNXT could handle).
Even with synths, between the ones that come stock in Reason and me owning everything by PinkNoise(better than any RE Synths I've heard btw), not much of a need.
As you've said, Reason falls short keeping up with newer age stuff. Even if they don't make a Kontakt Extension, they could at least bring the libraries that the NNXT could handle over, but I think the ease of pirating refills made them switch to REs. I'd love to one day be able to run
Komplete within Reason, I'd never look for another sound in my life...but that won't happen...other than running battery drums in Kong, lol.
