Dr Kawashima the boffin behind Nintendo's absurdly successful Brain Training franchise has revealed that a third game in the series is currently in development.
According to Kotaku, neuroscientist Dr. Ryuta Kawashima broke the news in his new book, Goodbye Brain Boom.
No precise details are offered as the doc explains he has a confidentiality agreement with Nintendo but he does reveal that CEO Satoru Iwata didn't want to release another game in the series until they could achieve "something special".
Could that special something be 3D? We wouldn't bet against it.
The last game in the series, More Brain Training From Dr Kawashima hit the DS in 2007. Eurogamer's Dave McCarthy got his red pen out, awarding the game 8/10.
The good doctor is also bringing his mind games to Kinect. Prof. Kawashima's Body and Brain Exercises launches on Xbox 360 early next year, courtesy of Namco Bandai.
