Don,
Your points are well made. It would be hard to listen to any particular piece of music and say, "Hey, that's a Triton Pro X." But I can nearly always tell when I'm listening to a Tron (sampled or real) because the sounds are so unique. I just think that beyond a few improvements, such as improved noise suppression and perhaps built in effects processing, it could become quite pricey.
