Apparently these are first in-game screenshots of Gears 2 I found in another forum. The source seems to be from Game Informer, where in the latest podcast, the editor says the graphics are mind-blowing.

If these are true screenshots then we are in for an amazing amazing game, I never doubted that anyway but this look crazy.

That's concept art i believe.

Edit: apparently not then 

Nope, these are screens from early builds of the game. These pictures are from Game Informer.

Some of those pictures are amazing. But, like all screen shots from early builds, I take them with a grain of salt.

First screenshot looks amazing , the detail is incredible.

If these are actual IG graphics then I might have to consider picking up a Pro round it's release.

I'm guessing they are target renders.

Second two are no good, if they are in-game screenshots.

First one, if achieved with a high smooth frame rate, is really nice. 

Grapically it'll probably be something like Mark Rein has intimated: Gears 1 < UT III on PS3 < Gears 2.

wow, the first sc is amazing.
So much details, no aliasing.

Damn those look awesome.

for the first pic; i really dont want to fight one of those

I have no doubt the game will look that good, but those are not "screen shots". The aspect is wrong in the first image to be from the angle of anyone playing.

I can't wait for this game! :)
