IGN believes that Killzone 2 is quite choice

[KBG29]

To everyone saying "oh 720p, the 360 can do that" yes it can, but only to an extent. Last gen every console did 480p, but a lot of Xbox games couldn't be done on PS2. This gen is just the other way around, both systems can do 1080p 60fps, but what makes the differance is what they are capable of at that resilotion. Killzone is an example of a game at 720p that the Xbox just can not do at the same quality, same as GT5 is an example of a game at 1080p the 360 could not do at the same level. That is not to say that the game could not be done on the 360. Every game that comes out for the Wii, PS3, and 360 can be done on all three systems, plus all three last gen systems.

If Sony was doing an exact replica of Halo 3 no changes to graphics, AI it would run at 1080p 30fps easly. The reason Killzone is running at that rate and resolution, is because of all the stuff going on. Everything is just at a higher level then any other game. Their are more polygons, more physics, more effects, more lighting, more sound, and more caos going on in every screen than in any other game ever made for a home console.

Their is no reason to try and fight about weather or not the 360 is more powerful than the PS3 or visa versa. In reality they from a CPU GPU stand point are equal, however, the PS3 is the more flexable system, because of the ability for the to to work together. Once Dev's learned to use them to their advantage as Polyphony, Naughty Dog, Guerrilla, and Insomniac have done PS3 games will all be better graphically than the 360, and it will be by a bigger margin than XB to PS2. You just have to look at what Sony did with the much weaker PS2 chipset with the same design compared to the much more powerful chips of the Xbox. Games like God of War 1, (especially 2), Gran Turismo 4 (1080i 60fps), R&C, and Jak were all very comparable to the Xbox games because of that design.
