The video itself is just a bit of a goof as it shows a virtual version of Philadelphia Phillis pitcher Cole Hamels (a known fan of Infinity Ward's previous games) getting blown up by a hailstorm of grenades. However the "sponsor" that is written out at the end of the video can be taken to be . . . something else when you use the first letter of each word.
Naturally we have emailed Activision and Infinity Ward to find out if that "hidden" message was intentional.
Update: The video has now been pulled from YouTube
