Re: Replacement for Blu-Ray
They're trying to make streaming the next big thing. But there's too many people in this country that don't have access to broadband, so streaming is out of the question for these people. If they can't reach the majority of people, it won't become mainstream. Blu ray will probably be around for a long time. They may can go higher than 1080p for the video, but I don't know that the human eye can see the difference anyway.
As far as writing to discs vertically, they already do that. It's my understanding that blu ray discs have 3-4 layers or more of info. That's how they get so much on the disc. DVDs were only dual layer.
