MisterMe, probably not to be honest. Technology tends to either go up in price or remain the same for years, especially as demand increases and production costs decrease.

Seriously though, it shouldn't take much thought to realize DVD authoring will (and has) followed a somewhat similar path as CD authoring technology. Cheaper disks, faster burners, etc... I remember when 2x CD-R writing was insanely fast and I envied a friend of mine who had one while I didn't... Grrrr!
I'm still not sure about the DVD stuff though. I really want to bite now, but I'm not very satisfied that there is the whole '-' clan and the '+' clan... I would feel a lot more comfortable if there was a single DVD burning technology. But that's probably just me. Cheers!
