"I have confirmed to all employees that I will be leaving at the end of December and not making the move to California," Harrison told Reuters.

Harrison began working for Nintendo in 1992, and would not reveal his future plans to Reuters. Speculation has been rampant among industry insiders as to who is going to take Harrison's position, and competition for the job is said to be high, given Nintendo's recent success.

Along with numerous other employees, marketing VP Perrin Kaplan and PR director Beth Llewelyn have also been rumored as leaving Nintendo once the company makes the move, though this has yet to be confirmed. Job postings on Nintendo's career site reveal openings for both Kaplan's and Llewelyn's positions in Nintendo's future Bay Area office.
