Plextor's Blu-ray / HD DVD combo drives still on the way

Oh, how things have changed since Plextor originally announced its combo HD DVD / Blu-ray drives would ship in February. Probably due to the end of the format war, the PX-B920SA and PX-300SA slipped a bit but should hit store shelves by the end of this month. The cost of hanging on to HD DVD compatibility? The all-HD media playing, 4x BD-R / 2x BD-RE / 16x DVD±R burning PX-B920SA will cost $599, while the PX-B300SA (hold the BD-R/BD-RE, please, we're on a diet) is $499.
