Kaplan did not give an explicit reason for her departure, saying only, "I finally will be leaving Nintendo at the end of the year. Until then, I am focused on getting a great transition team in place and handling all of my normal responsibilities as well." It had been speculated that the marketing exec trio -- now all officially on course to retire -- would leave Nintendo after plans to relocate the company's PR headquarters from Washington to San Francisco and New York were revealed in May. But this theory remains pure speculation. Think about it: there are plenty of other circumstances that could have prompted Kaplan's resignation ... well, actually, we can only think of one.
