No, they were probably going to buy it to play on proper servers, now that they've completely ruined the game there's no reason to buy it anymore.
Nail, meet head.
Some of the tweaks to the MP aspect of COD:WaW were a little controversial, and disliked by some, but it is still essentially the same model, dedi servers, console, etc - now they've hobbled the MP version of COD into a gimped n00bs forever system, they've lost any chance of proper gamers buying it.
Maybe they're hoping more *casual* gamers will pay top whack for it, realise it's rubbish and just blindly buy the next version based on how many awards it wins. (which incidentally I hope it wins none)
Either way, I forsee a very short lifespan to this game. I'd bet money on it.
