I remember a while back their being a few nuggets of info floating around about possible new drives but I'm not sure it still applies anymore because obviously things changed.
At this CDR-Info link their was news of BenQ's forthcoming drives.
- BenQ DW1600, 16X DVD+R, 2.4X DVD+R DL, no DVD-R writing
- BenQ DW1620, 16X DVD+R, 2.4X DVD+R DL, 8X DVD-R
- BenQ DW1630, coming around October, 16X DVDÂ±R, 8X DVDÂ±RW, 4X DVD+R DL
- BenQ DW1650, same specs as DW1630A but with SerialATA interface
Now the 1620 became the 1620 Pro so the specs of the 1620 and 1630 merged, a Serial-ATA interface version if still on the cards would be nice though I hope they don't just do what some of the others have done and stick an off the shelf PATA->SATA converter to the back of the drive inside the casing.
Some info from BenQ themselves was posted in this thread and it seems a 1640 was planned for the end of November which of course didn't happen still a 5x DVD+R DL, 8x DVD+/-RW and a SATA drive would peak my interest...
