One clarification from my previous post. When I said the "online maps" will be free I was referring to the ones that come with the game. You won't have to subscribe to have access to them and still be able to play online without subscribing.
The additional map packs will be included as part of the subscription price they are charging. However, the maps won't be "exclusive content" to subscribers. You can still purchase the add-on map packs just like you would normally get to. I would imagine they might give "subscribers" a exclusivity window but they have not been clear about even doing that.
So, at the end of the day you are paying $7.99 a month to get stats, videos and possible custom "cosmetic" stuff. They say they are including the add-on map packs but in reality you really are paying for them just after one month. Multiply that by how many months you have it and they better damn well include it in the price.
It's a scam because you can't tell me that each user paying 7.99 per month isn't over kill for paying for a server that basically stat tracks and posts the information. They are going to make money hand over fist for anybody that falls for this. The money they make off of you will pay for the map packs, the server and then some. Activision's Quote - "Mr. Dyer said he is "very confident" other publishers will follow Activision's lead. "There's money to be made there".
I think they are really targeting the console market. I can't imaging a big market for this in the PC world. There are to many tools you can use to do your own stat tracking for PC users. I used to run a few on my gaming servers way back when.
