We already know for a fact that HD-DVD is on the industry's 'deathlist' now... Several HD-DVD exclusive studios have switched to bluray and even MS is comining out with a blu-ray external drive for their Xbox 360
As for Toshiba, they've pulled the plug on their HD-DVD production (at a cost of hundreds of millions) and what you're buying here are the very last Toshiba units you'll get.
