I was watching the Colbert Report and he did a segment on some tie-in with Doritos and Mountain Dew and MW3. Apparently - they've set up some kind of double XP program for buying their products. Here's more info:

I only wish there was a tag that went with it on any one who gained XP doing this that would appear next to your player name to advertise the fact that someone felt they had to buy their way up!

You know someone is going to buy $10,000 of junk food to rank up.

(sigh)  There's a good healthy promotion.    I can see the congressmen and women now complaining that not only are we playing games that are leading to the end of civilization as we know it, but we're going to get ultra fat and be a burden on the health care system as well.  Oog.

I have 2 hours of Double XP as of now. I'll eat the junk now and I promise to eat healthy during the holidays, if it gives me an edge.
