At least from here, CeBIT was pretty uneventful as far as new optical drives go. Sony NEC Optiarc and Samsung did have a few new drives on display though. Specs and pictures borrowed from PC Watch
First up is the AD-7191A from Sony NEC Optiarc. The drive sports 20x DVD±R, 8x DVD±R DL, 8x DVD+RW, 6x DVD-RW and 12x DVD-RAM writing speeds. Google's translator sucks but it looks like it might read DVD's at 20x.
Sony NEC Optiarc also had the AD-7173S on display. I can't tell, but I think it says that it supports Serial ATA and Labelflash. Maybe 18x DVD writing speeds too?
They also had four slim Blu-ray drives for notebooks. The BD-5710S (SATA and slot load), BD-5600S (slot load), BD-5500S (SATA and tray) and BD-5500A (ATAPI and tray).
