im in the same situation,im so bored with cod4 you wont believe it.
ive even installed the first cod just to go back to ww2 game because i dont think you can beat them,the graphocs are nto as good but the gameplay is alot better for me anyway.
im just waiting for cod5 aswell,il probably download the demo first before buying it.
theres quite alot of games been released within the next two months.
