New Uncharted 2: Among Thieves Multiplayer Demo?

I was looking at Uncharted 2 at ebgames.com when i noticed that there was a bonus for pre-ordering at ebgames/gamestop. What surprised me was that the bonus was another Multiplayer demo! This multiplayer demo will be available to download and play from 8-19-2009 to 9-27-2009 and is exclusive to ebgames/gamestop
