I never said the blu ray's "failed". I paraphrased what I had read about them underperforming. I'm guessing you just don't like the possibility that what Robert Burnett said may in fact be true. I think he'd be the last person to put out false or misleading information to fans.
(edit - If he has ever put out false or misleading information in the past, I'd like to know. If there is any verified quotes or bits of information from anyone working at CBS Digital about this topic, I'd love to read it.)
But lets just say for arguments sake that what he said isn't true. Then, why wasn't DS9 and Voyager's remastering put right into production? If the profit or financial motivation is there for them to do it, why hasn't it happened?
My answer is - because there is not enough financial motivation for it to happen.
As far as the HD masters, whatever may exist for DS9 and Voyager in syndication/home video/streaming is at best up-rezzed standard def material. What shows up is no more "high def" than my DS9 dvd's being upscaled off my Oppo.
