CNET had an interview with Sony about TVs and Blu-ray. Here's a snip from the article:
Looking ahead, you're only just getting into Blu-ray. How do you see the future penetration of the format compared with DVD?
Glasgow: That's a good question. DVD took 10 years to really penetrate. We're now in the second year of Blu-ray. My guess is it will probably happen a little quicker in terms of penetration. The pricing is already coming down more quickly than DVD came down. I don't think it will take as long as 10 years, but I don't think it will penetrate to the same percentage because there's a couple of conflicting forces. Certainly, people that want the best picture are going to want it, without a doubt. People that are OK with upconverting DVD players, which is somewhere close to 600, 650, maybe 700 (lines of resolution)--that's not a bad picture either. So a lot of people may be happy with an upconverting DVD player. And (Blu-ray) may not turn over, it may not penetrate to the same extent, because (DVD) was such a big medium change from tape.
But I see it being the major format. It's won the war, that's done. Now it's a matter of: Can we provide an exceptional experience? Can we provide a social part? And can we involve the overall community in, let's say, designing applets and coming up with new things that we can't even think of today?
