Wow. No need to tell the guy to die or anything. It's his franchise, let him do what he wants with it. If it fails, it fails, nobody is making you play it. I personally wouldn't mind if it meant better support and free DLC and all that. I figure if you payed the 30 bucks for the two map packs in MW2, and let's say they charged 30 bucks a year for the subscription, it would even itself out.
I couldn't see them charging more than $50 a year for the subscription, and if there are the rumored two more map packs coming out before the next game, priced at $15 each, you would still be saving money if you are a hardcore fan. I don't agree with his decision myself, but let's try to be adults about it at the very least. I think he should realize that kids don't have the disposable income to pay a subscription to a game like that (especially if they are playing WoW or something already), and I can't see many parents wanting to pay for a game subscription on top of paying for XBox Live.
