Hitachi and Mitsubishi have both announced today that (in Japan at least), they will be releasing single layer HD DVD-Rs, with RW and dual layer blanks to come later this summer. Still no recorders announced, but with their importance in the Japanese market and media now scheduled, they cant be very far off.
Impress approximates the price at about 2,000 yen ($17.75 US), which is about the same price as single layer Blu-ray media. What the press releases dont seem to say is whether this media is 1X or 2X speed rated; because of the difference in the specifications 1X (36.55mbps) media could still play HD DVD content, but would be a slower burner than the Blu-ray drives that are coming out rated at 2X (72mbps) or higher. Impress only mentions the Hitachi as being 1X.
