I don't really care either way. The only time I'll play CoD games is when a friend gives it to me to borrow (which is funny, because I've never asked to borrow games from my friends, they're usually just like "dude you should play this etc."). And then I only go through the single player campaign. Fun games to waste time I guess, but nothing I'd want to purchase.
I really can't believe the nerve of Activision this time though, as far as their subscription-based gimmick goes. It's already enough that I have a gold subscription to Xbox Live.
