I realize the article is recent, but it's old news.
Any fan of MW2 has known of Kotick's desire to go in a MMO fashion with Call of Duty for awhile. At one point it was believed that one of the studios making a Call of Duty was doing just that, while the Treyarch and Infinity Ward did their regular rehashes. WoW just brings in too much money consistently and others have tried in vain to reproduce the results and failed. MW looks like the one franchise with the online base, to possibly replicate that success.
As the Big Pond writer takes a position to spur debate, it isn't wholly unbelievable to think that Activision wouldn't change up the formula to support a MMO. Add things that would make an MMO seem more appealing than what is now offered. Dedicated servers, possibly beta testing, or anything to reduce the appearance of lag, completely customizable soldiers' appearance, specific clan uniforms, blah, blah, blah, you get the idea. At first shot Kotick isn't stupid enough to just lift the MW franchise and plant it as is, as a MMO. It will be a different enough animal to make it an option, that way Activision can continue to churn out CoDs like Madden games, with their now obligatory high priced map packs, and maintain that cash cow as well.
Although I wasn't too crazy about the tone of the writer, I do have to agree with him on an important point. The fanbase has encouraged & empowered Kotick to take this route. When all the crying, wailing, & gnashing of teeth was done about the price of the new map packs, millions still voted with their wallets and bought them. That is all Kotick needs to hear, MW2 is like crack, and he's the happy legal seller. Fans will buy anything for their fix. Sure they will cry & moan that they won't pay, but the percentage that actually don't... too small for him to care about.
I'm one of those too small for Bobby to care about. I admit I will probably get Black Ops, and like MW2, I'll play until the 1st map pack and disgustedly move on. Bobby doesn't care, as long as I am one of the sheep buying Black Ops on 11- whatever- 10. Bobby Kotick is a very successful businessman for a reason, he knows in this day in age of movie sequels, Harry Potter & Twilight book series, it's wise to maximize your successful properties. We can all sit back and say someday it will come back and bite him in the @$$, but until then, Activision's investors are cheering Bobby on.
