This is pretty fascinating, if only because only about two months ago, an analyst said that CoD couldn't go the way of GH. Of course, it will, make no mistake about it. You can't just keep running the same formula and expect people not to catch on eventually. If the series wants to maintain top billing as long as possible, it's going to need to change and evolve. Every notable series has declined. Doom, GH/Rock Band, Grand Theft Auto, etc. I don't know why anyone could possibly believe that this won't suffer the same fate. And the more iterations they release, the faster it's gonna happen.
And, my disdain for CoD aside, they need to get rid of Treyarch, stat. Those people are the some of the worst tech guys I have ever seen. They can't fix a bug. And the head of Treyarch stated several times that the PC version of the game is as good as the rest, but the truth is, it's a bugged out piece of shit. I loved Modern Warfare, and I would even take Modern Warfare 2. But Blops was real shit. I can't even believe the game is still selling for full price. But, it's good business to keep selling it at that price till people actually stop paying that price for it.
