Why would anyone pay that much? I paid that much for an entire HP desktop with a LG blu-ray burner 6x BD-R (granted it was refurbished). Remember when DVD burners were $400+? Sure seems like a waste of money... especially for the cost of media.
I second Luscious. It might as well be a 100x burner, for the media that's available right now. You'll never find 8x Blurays outside of NASA or something anyway.
I'm not sure what's worse, showing up too early or too late, but either way there's not much reason or demand for this yet. Not sure when the average user would see this as neccessary, but I doubt anything above $200 is gonna generate much interest.
While this drive isn't peticularly game changing the fact companies are pursuing this can maybe spur the disc manufacturers to push out 8x discs faster. If more companies push the envelope soon there will be nothing slower than 8x =)
