I don't think it will become that commercial,... To compare, I do listen to some other music too, and one of them is rather extreme metal.
People in that scene were also affraid of becoming commercial and stuff, but in the end the music isn't made for the mainstream. Just listen to most psy trance, it goes way deeper than the average tiesto or RnB track. I don't see many top of the pops lovers get into psytrance "With all those weird looking hippie people".
