Well, could have told you this. How many millions of PS3's have been sold? 3, 6...? How well does Blu-Ray sell? Sure they are beating HD-DVD (right now), but if more than 40% (which I honestly believe to be high) were buying Blu-Ray, you'd see sells in the millions, not hundreds of thousands.
Again, I've said it before, and I'll say it again, Blu-Ray and HD-DVD aren't going to move much, and having two formats just makes the possibility of one or the other winning, that much more unlikely. IMO, neither will win, by the time they start selling in numbers that really mean something, something else better will come swinging in and take the mantel of the next generation of home entertainment delivery.
Now, onto the main jest of the thread, when they are now selling digital SD TV's, the prospect of HD really ever becoming something main stream in the next say five years, is not very likely. Additionally, game consoles are just that, game consoles. Most won't buy the most expensive (or second in 360's case) because of its HD capabilities. The majority of consoles are sold and bought for kids (those under 16) and therefore, either kids don't care, don't know, or parents just don't want to spend that kind of money. Hence why Wii has done so good. The ones that do buy PS3's and 360's, as this poll suggest, just don't really want more than the latest gaming machine. (home entertainment, HD-DVD or Blu-Ray, HDTV, etc. are not their concern, at least the majority).
