The reason there are 2 developers making CoD games is that Activision own it and want to see a steady stream of revenue - that means 1 game a year. It's pretty much much impossible to make 1 CoD-scale game every year for just one studio, so two developers work together releasing alternating games each year. (can't say I really blame Activision for wanting this, alledgedly MW2 cost upwards of $50 million to make, heck i'd wanna see some money back as well)
