Here's some quotes from Gaming0age(not the forum,the actual site) about the games shown:
"Another tech demo was shown and co-developed with Ninja Theory which had a thousand characters reacting to complex rag doll physics. The graphics were all PS2-caliber with nice post processing effects such as depth of field"
"Warhawk, while looking great, was essentially a barren section of ocean with a lot of fighter ships (they were aiming for a hundred for the final game) going around destroying larger vessels and some nice looking water (wave simulation with procedural animation) and clouds (volumetric raytracing). Overall it was a great demo but a far cry of what was shown last year and gave a nice sobering introduction to the rest of the demos which was shown towards the end. Fortunately it will be playable at E3. "
"Next up was Motorstorm and just like Warhawk was no where near the E3 target render. The car models and physics were decent although the texturing and the environment was PS2 level of quality. The real star of the demonstration was the deformable terrain which worked quite well with the physics of the cars. The demo also had HDR, post processing effects, and occlusion. "
"The next game was Resistance, the title formally known as I-8. Out of all the games this one was the farthest along but unfortunately the least interesting. It was your standard FPS affair with highly linear levels, decent A.I. and moderately interesting weapons. The lighting/texturing/modeling was all decent but nothing groundbreaking"
