Considering the Treyarch developed CoD: WaW has sold 11.4 million (not including PC sales) I don't think it's a complete loss if some of IW left the company.
Besides, leaving on account of having to develop a Wii SKU might be the most childish thing I've heard all year. Those founders of IW that left 2015 Inc did so out of financial purposes and to establish their own studio. 2015 Inc wasn't even owned by EA. It was a private studio. In fact, guess who published their first game....Activision.
