From the events the past few weeks, it sure appears that Blue-Ray has the clear advantage.
With MacWorld coming up this week, it will be interesting to see if Jobs embraces Blue-Ray. Rumors are out there that he may introduce something with a Blue-Ray.
Apple and Sony have a good working relationship. I would not be surprised to see Jobs announce an AppleTV or Mac with Blue-Ray support (especially since MS has thrown it's weight in the
HD corner)...
