Yeh, missing his point. He says blu-ray has 5 years to live but doesn't really give us a reason why. Just that some technology will replace it. What technology? The guy is talking out of his ass.
There is no technology at present or in the next decade that will replace blu-ray. But based on blu-ray technology being expanded to 500GB disc's does make it future proof. I don't see the demise of blu-ray anytime in the next 20 years.
