Although this article i found (whilst cruising on the web) does not feature the website I thought it would be good news for the killzone fans

A web site featuring the words "Killzone 3 beta login" in the url and heavy Killzone 3 branding has recently appeared.
It currently warns that users need to "sign-in and have the right permission to view the rest of the site." There is a field to enter a PlayStation Network login, but so far we haven't been able to gain access.

As a reminder, Herman Hulst of Guerrilla Games will be delivering the Keynote Address at GDC Europe next week. IGN will be there to cover all of the Game Developers Conference and the massive GamesCom conference in Cologne which runs from August 18-22. "
