They will be able to burn 50GB of data on dual layer media, at 2x on BD-R, but also DVD at 12x and CD at 40x. To be compatible with these 3 formats, each burner will feature 3 different lasers; the price is of course higher.
Both burners will come with the AACS current definition, and will support further firmware update when the final AACS format will be released.
