Blue-ray is around the corner for everything that currently runs dvd format, Video recorders/players, game consoles, computers. I wouldn't worry too much about copying or region blockage from this format, just like any technology that's put out, there's always a code breaker willing to tackle it. If blue ray is going to be the next big in your face tech, even more than the usual amount of hackers will be attacking it form every direction.
Has nintendo or MS said anyhting about there next format? More than likely with sony's move the others might join in on it.
