You’ve shown your ignorance of how business works.
Now let me enlighten you.
Having a larger installed base of blu-ray players carries lots of weight. People buy a PS3 for gaming then they start hearing about blu-ray discs as the next evolution of DVD but in Hi Def. They say, “hey I have a player, I’ll start buying some BR movies so I can see them in hi-def.” That increases the sales of blu-ray discs which is then used by Sony to show movies studios that they are outselling HD-DVD and the movie studio gets on board with blu-ray and not HD-DVD.
That is the theory behind what Sony is doing. Its risky, but if it works, they cash in big time. That is why they are selling the PS3 at a supposed loss right now.
And you can sit there and say “If Xbox 360 sold w/ HD-DVD…” but the fact is that they didn’t. I really don’t care which format of HD disc wins out. I would prefer that it was blu-ray as it will ensure the success of PS3, but I will just as easily pick up the HD-DVD player for 360 should that become the dominant format.
