Sega is confirming a shuffle of the top brass. As speculated, Sega Enterprises President Shoichiro Irimajiri will step aside to allow Isao Ohkawa, president of Sega parent company CSK, to takeover. Ohkawa is moving into the hot in order to oversee a massive restructuring of Sega's development activities. The reorganization plan, originally announced in November, will split Sega's interested into a total of nine separate units organized by region and specialty. Irimajiri will stay on in a vice presidential role to focus on the creation of a Dreamcast successor.
