I think the technical gains are much bigger for Uncharted 2 than it has been for Gears 2.
In any case Naughty Dog can only speak for theirselves as for example in theory it's possible to create a technically worse sequel.
Some developers will put more effort into their game tapping the PS3's potentials than others. Going back to my Amiga example, Ocean's games took good advantage of the Atari ST's strongpoints, but as the ST did not provide much additional headroom their later ST games did not see big advancements. As the Amiga conversions were roughly identical to the ST version, the same was the case for their Amiga games despite other developers achieved huge technical gains.
