What happened? Zampella is quoted as saying that they went ahead with Activision's wishes, stating, " . . . we'd get some dev kits for consoles in exchange for doing a World War 2 game. We always wanted to be on consoles and Activision saw us as more of a PC developer." Even for Call of Duty 4, Zampella stated Activision originally wanted yet another WWII shooter, saying "They were doing market research to show us we were wrong the whole time." Of course, Call of Duty 4: Modern Warfare turned out to be the most successful game in the series so far and Modern Warfare 2 is looking like it will be even more successful. Which proves that following "market research" blindly won't lead you anywhere.
