I have the same exact situation like a few of you. A handful of my buddies were going to get this game after watching the trailers of in-game footage, but then they tried the beta and shortly after the mission was compromised. I'll admit I was a bit disappointed too, but I knew this wasn't the final product.
Anyways, I guess they'll be sticking to MW3 exclusively now. Don't get me wrong, I love the Modern Warfare series (CoD 4 was the best), but playing a Battlefield game with randoms just ruins the experience. I'll probably pick it up though regardless.
