I think it will be the opposite.
With decreasing sales, everything will just get lumped togather in the "techno" section

Which is a good thing in a way.

There`s this fantastic second hand record shop in london I go to, and it`s techno section is just this huge mess of electronica.

I love it.

I just dig in sometimes and buy loads of cheap vinyl for like, 50p and a quid, that I have never heard of, and I get some great stuff.
