SithTracy, you know, I hadn't thought of what you mentioned about Yamaha before your post, but the more I think about what you said, the more I wonder about Plextor's fate!!!
Well, I'm not market specialist, but it makes you wonder about the future of Plextor. But there is a difference in Plextor and Yamaha's situation. Yamaha had other areas of the business that made it money; Plextor seems to have it's only strength in optical storage, though they dabble with video capture, but that is a tough market to jump into.
The other think I look at is Plextor going to BenQ to get into a budget market, but I feel the PX-740A was priced to high and stripped of features. Being the researching type (as most of the forum dwellers are), I bought a BenQ DW1640, spent less money and got the better offering. I have mixed feelings about Plextor offering rebadged drives... It cheapens their trusted name in a way, but I imagine they are making efforts to stay afloat by doing it.
I hope Plextor continues to provide great products, but looking at their forthcoming line-up it does make you wonder.
