I live a mile and a half from sony’s Terre Haute plant — its largest Blu-Ray plant in the world — and know several of the engineers who helped develop Blu-Ray. I really doubt that this is the end of the development process. I attended a presentation from the plant manager in March, who outlined several improvements scheduled to appear in the near future.
Terre Haute? I live in NW Indiana here! I used to work in Indianapolis...small world after all...:-)
