i've got a feeling the entertainment industry may make sure that the dual layer media stays expensive.
also, think how long it took for dvd-r media to get to about $0.50 - about 3 years!
it's a bit absurd that you can buy a burner for the cost of 4 discs!
also does anyone actually make 4x dl media yet? i thought it was all 2.4x, and i wonder if dvd-r dl will make the prices of dvd+r dl fall?
