The landscape is not likely to come to anything for at least a couple more months.
After that we will have a better idea of which "Standard" is gaining market/mind share.
DVD-RW currently has a slight lead:
Came out first, prices on recorders already starting to drop, supported by the DVD Forum, currently has both
R (recordable) and RW (Rewritable) media available.
But DVD+RW is in position to make a good showing.
Took more time to work out specification, better for data storage vs video storage, potentially as "compatible" with
commercial DVD players, supports additional features for saving data, more compatible with CD-R and CD-RW,
created/support by some of the big names from the DVD Forum.
