Maybe they just want to unload all of those dogged units from the big stores in anticipation of Sony's new players. I think BD nuts would be more apt to spend the big bucks on something that isn't trashed in the blogs.
Sorry, I tried to post a link earlier, but it got messed up in the translation. Go to the Costco site and do a search for HD DVD. The Toshiba will come up at $449.
I was just looking around at what they had at mine 2 days ago and there was neither BluRay or HD DVD. It is good news if they are selling them online. With Costco's return policy I think its better news for the Toshiba than the Samsung.
