You're welcome for the info. =P

Just saw a short commercial for  MW2 during the Denver/Dallas playoff game.  They showed a snowmobile scene, scuba scene, what looked like a firefight on an LZ, and what looked like a guided bomb hitting a target.  The commercial ended with a message of a world premier May 24th during the basketball game.
