We have XBOX 360, PlayStation 2&3, the Nintendo Wii, and all with various degrees of success have continued to move forward. So if I speculate that Toshiba and Microsoft may stay with HD DVD, then there it is. That would help all those customers that bought HD DVD players.
We've already heard reliable news that MS is actually working on a Blu-ray add-on for the 360. A good way to compete against the PS3. And likely Toshiba will release a combo player by Christmas if not early 09. HD DVD is history. The money is where the blu is.
