Sega today threw in the towel on games console production, announcing a restructuring of the company to focus on software production. The move could signal a downturn in the games design market for designers - at least until newcomer Microsoft enters the fray with Xbox. The new business strategy, which is due to be detailed Wednesday evening in Tokyo, has three main parts: the move to become a platform-independent video game publisher, a focus on networking gaming technologies and the licensing of its Dreamcast chip-set to other companies. Sega said it will adopt technologies such as Java to take its games to new platforms including handheld computers running the Palm operating system and Motorola cellular telephones. Games for both those devices are due this year, it said. We'll update this story as it breaks throughout the day.
