Thinking about it, PlayStation probably would survive and thrive long after ES and CoD are dead IPs, and provide better alternatives, but the point is that it is Xbox that has to give gamers something new that they want to entice them to buy their platform in Nintendo and PlayStation numbers. It really is that simple, and buying Activision is at best bad for CoD players if MSFT kills the franchise, and at worst the means of giving the keys of the kingdom to the weakest platform to starve out the competition like a VHS and Betamax situation, where Betamax couldn't get all the films on the format in time with VHS.
