Good news for us SXS users is that JVC has adopted it as standard. Prices will surely plumet.

MacVideo - News - JVC camcorders to work with SxS media (http://www.macvideo.tv/news/index.cfm?email&newsID=104354)

This is really cool news. Congrats to Sony/SanDisk for licensing their technology. This will indeed decrease the price of media quicker since more users/more buyers = cheaper as time moves on.

....we can only hope.
