The error came from the Japanese article, where, at the time of our publication, the editor at Nihon Keizai Shimbun misconstrued a comment by Wada in regards to the licensing of the Unreal 3 engine and its use in upcoming games. A retraction was later issued at Nihon Keizai Shimbun, and, once we discovered the retraction, we modified our story. We apologize for the issue and the inconvenience.
