GamePro has revealed the cover of next issue, with nice presence in Killzone 3, nothing already knew, but one thing grab the attention, a name, the name of James Cameron.

How Nazi Germany, Mother Nature and James Cameron helped shape the creative direction of Killzone 3

This is a good thing, given the indisputable talent of Cameron, especially in the creation of environments of the game.
Killzone 3, which was revealed by the leaked scans of GamePro, will have the first trailer at E3, and should be out in early 2011.

That doesn't really say anything, for all we know, he could just have been a source of inspiration without him ever being a part of the development.

I think it's pretty likely his work was a source of inspiration rather than 'ole Jim actually having directly given input.

You never know, and with the 3D maybe he'd be a bit interested, but it seems pretty unlikely he'd have time right now.

Not sure. If he did, this game is just getting better and better
