Sega of Japan have launched a new teaser site for something called "Project Ringo". The female silhouette featured in the teaser has a funny hair do and plays with a ball (or apple?) and the short teaser ends with text "What happens? ---next_2.24". So its safe to assume we will know more in about 12 days. It has been suggested that it might be a game for iPhone as Ringo means apple in Japanese, but nothing solid is known about possible platforms at this point.
