I'm going to be an a$$-hat and come right out and say this; I think that you're determined to see the PS3 and its games in a bad light, no matter what. I think you've already made up your mind, and that's just the end of the story.
Which if that is true, is completely fine. You're entitled to have your biases without explaining or justifying them. And if I'm wrong, then I will quite happily eat a truck load of humble pie
Regarding Uncharted. I can SORT of see where you're coming from on the graphics front, but where you're seeing "just higher poly character models" a lof of us have seen it as "thank god it's more than just brown and too much bloom". The environments look lush and colourful....it really is something when you get to look out over a large portion of the island from a certain point.
Naughty Dog went for a very specific art-style with Uncharted, and I think it looks great because of it. Who needs the "mostly-brown" sludge that a lof of games seem to have these days? I think you just want the overly busy textures (an art-style that I personaly hate) that Capcom seem to love so much....not to mention the extreme amount of polygons they can use on games like RE because they're rendering almost nothing.
A lot of the power has gone into something VERY important, something even GTA has had to deal with (using NaturalMotion) and that's the animation system. Uncharted probably has one of the most complex in-house animation systems that I have ever seen. There are very few times when Drake's movements look artificial or where there is glaring "popping".
Even then....the PS3 isn't being fully exploited. For me, Uncharted was the first step towards what a PS3 game should be...both technicaly and in terms of good, soild gameplay.
Right....back to MGS4 for me.
