I think acid will be born again soon enough. People will always want hard music for the brain, but i think standards have changed a bit. If you can put out some acid tunes that have strong production, and innovative programming, I'm sure people will listen.

If you listen to tracks in the Minimal/Tech House/etc. scenes, there is still quite a strong acid influence in effect. If you maintain the qualities that make these tunes popular and also crank up the acid, I'm sure there's an untapped market to explore.
