Según IGN esto se nos viene en KILLZONE 2:

Much more interaction with NPCs such as pulling a hurt comrade out of the line of fire and other things.

Better face emotions and other details.

Completely non-linear levels.

Destructable environments.

Land, Sea, and Air vehicles can be used.

Extremely customizable online play


y PSM acaba de decir algo sobre Playstation 3 y Killzone 2, que pondré aquí

Here's the deal: None of the game footage was taken from software
running on systems using the final PS3 graphics chip, the reality
synthesizer (RSX). As of early June, developers have just received
development kits that have a single NVIDIA GPU near the power of the
RSX. Most of the game footage at E3 came from "alpha" systems, which
are basically custom IBM PCs containing an early Cell processor and two
Nvidia 6800GT graphics cards working together in SLI configuration. The
most stunning demo, Killzone PS3, was from the actual game engine
running on an alpha kit

En otras palabras, KILLZONE 2 según PSM, estaba corriendo bajo un kit alpha..quiere decir que Killzone se verá mejor que como lo vimos
