New DVD-RAM not compatible with previous drives

DVD-RAM media have usually not been the main product receiving technology improvements in order to catch up with the burning speed race. But the DVD-/+R/RW media have reached their limits, and manufacturers are now proposing new DVD-RAM media with improved performance, but at higher cost.
For this purpose, the DVD Forum has validated the DVD-RAM2 format and its corresponding media could support up to 16x burning speed (going through the usual 6x, 8x and 12x).
But this performance improvement has a side effect: such media will not be compatible with the current DVD-RAM drives that can burn only at 5x. It could even be dangerous since such media inserted in the current drives could be ejected while rotating at 1600rpm...
DVD-RAM drive manufacturers should propose firmware updates before those new media arrives in our shops.
