LG Germany has announced that it will ship the GGW-H20N, 6x BD burner with HD DVD read support, in Q3 for about €400. That's almost half the price of what LG's first gen hybrid drive, the GGW-H10N, cost in Germany now. Not bad! (but I guess LG noticed that no one bought them at that price)...
It looks like the GGW-H20N will also be the first 6x BD-R burner (and according to CDrinfo it will also support 4x BD-R DL writing, 3x HD DVD reading, 16x DVD±R writing and 40x CD-R writing).
Currently Lite-On's drive seems to be the cheapest BD burner in Germany for about €475.
