I'd be inclined to agree.  Particularly the bit where you said...

"...With 300MHz DSP that's more than 100 instructions. I admit there is 
a
space for a lot of computing indeed. OTOH at that horsepower you can
make nicely sounding synth voice using constant sample rate."

Yep, you could surely run a 16-voice polysynth complete with 3 
oscillators per voice with a decent 32-bit 300MHz DSP.  And all this 
using well established VA algorithms and fixed-rate wavetable playback 
techniques.  Novation released the A-station donkey's years ago now, and 
that was an 8-voice VA polysynth with 3 oscillators per voice, chorus, 
reverb, vocoder, EQ, delay etc, all implemented on a 100MHz DSP56000 
series chip.
