Well, it's official. Even if you didn't want to believe it, here it is. The teaser trailer above will have to suffice. The logo matches up with what we've seen previously so I'm inclined to say that the leaks earlier today were spot-on as well. I've said it before and I'll say it again:
Update: Here's a second MW3 teaser titled "Germany."
And here's "3ngland." This whole "3" is going to get tired real fast.
