I do get it, but money talks and all that, the Name Call of Duty itself has become it's own entity, buyers flock to the name (it's like the McDonalds of gaming).. It doesn't matter to kotick who built it up to be that big, he just wants to sustain the juggernaut and get new people at the helm, didn't IW want to work on something else after MW2?... I doubt once the initial handover takes place that the sales will take much of a dip,but as for quality wise who knows (probably)....
Also more Savvy Gamers will vote with their Wallets, the Little Teens etc will rabbidly flock to the digital crack.
Kotick just cares about how best to milk it, I bet this shit was in Planning from the moment he took over.
