I'm going to go out on a limb and say that most of the people here who support Wii are downplaying HD as much as they can, saying that its not that big of a deal
And I'll say that's total BS.
Just look at Japan : it should tell you right away that HDTV sets are not what drives console purchases.
Now, I have a Wii, I support the Wii, but I sure enough don't downplay HD. Saying there's not enough HD contents broadcasted in my country, HD sets are still incomplete option wise, HD sets are full of flaws depending on the technology used, HD sets are still expensive compared to SD sets, that I won't buy a HD set as long as my SD set works, and that I won't buy a HD set smaller than my current SD set (52"), is not downplaying HD : that's just mere common sense.
So where you see Wii owners downplaying HD, I see people with lots of common sense that don't buy a game console just because it outputs HD and HD sets is the future.
