Hino said the current trilogy will close out with “Professor Layton and the Last Time Travel”, and a new one will open with “Professor Layton and the Flute of Malevolent Destiny”, to be released in Japan.
“The new trilogy will also be based around solving puzzles, but will also include greatly improved bonus modes so I think that players will be able to enjoy the games for even longer. We currently have no plans for a Wii release,” Hino told ONM. So, there ya go.
