According to a report in Japan's Nikkei Industrial News, publisher and developer Sega is onboard to create software for Nintendo DS, a dual-screened portable set for release later this year by Nintendo. Sega's president Hisao Oguchi also confirmed that the company is ready to make software for Sony's forthcoming PlayStation Portable (PSP) system.
Not that it's entirely unexpected, given that they've released something for every platform being sold in the US today.
