Sega has announced that it plans to reorganize its development studios. Currently, Sega has nine R&D studios, but it plans to close four of them and build two new ones. By restructuring, Sega hopes to produce blockbuster titles more efficiently. No further information on the closures has been released at this time, but the details of Sega's plans are expected to be revealed at the company's executive meeting at the end of the month. The reorganization is expected to begin in October.
