It is difficult for me to imagine that this petition -- or any petition of this sort -- is going to make a real impression on the record labels. If people had bought SACDs (or DVD-As or whatever), the record companies would have made more and more of 'em. But folks have largely ignored the newer formats, and the labels have listened to the attendant hush from the market. It's doubtful that a petition, even if a squillion people sign it, is going to change anything.
