Nice thing about Blue-ray is that Japan will be region 1 with the US so import of Disk wont require region free players. I been waiting for this one for about 6-7 years. As I had a customer that would and call to tell me about some of the improvements that were going on. If he wasn't breaking any NDA then he had some good inside sources. (I did find the information about 2-3 weeks later).
HD doesnt have region coding.
