I'm afraid you're completely wrong with your estimation.
Let's hypothetically assume a huge control surface is possible, so John could release both the Solaris and the Quantum Wave...
Which one would be sold more, if advertisement would focus on the fact that the latter is the most trustful and most usable version of the PPG legend ?
I've read about an interesting sales research recently - people didn't care about the price at all.
Their only concern was the 'relative' amount it was off regular price.
Someone who considered a 'regular' 1k Euro TV as 'too expensive', would gladly spent twice the amount if the 'original' price was (say) 6.5k
the PPG Wave was a famous instrument and it was unaffordable - you literally 'spare' 5K Euro on it's virtual incarnation.
Nevertheless the Solaris is a phantastic synth and has the advantage (for live performers) that the complete sound palette is united under one hood.
But it's unknown... as was NOAH...
cheers, Tom (I really regret this comment, but imho the facts look like this)
