Electronic dance music will always be around, it's been here since the 80's and is continuously evolving. I was mainly talking about the excessive commercialization/Wall Street-ization of the music. I.E. SFX Entertainment buying out Beatport and all these festival promoters and having an IPO and all that jazz. In North America/the UK, electronic music tends to wax and wane in the mainstream consciousness - it'll be very big for a while, die down (the "die down" period is usually when the most interesting records are being made, naturally), then get big again...
