Konami has revealed a mysterious 'Mii Training' mode in Pro Evolution Soccer 2009 for the Wii, although they're keeping the details under wraps for the moment. "We won't talk further about that," said producer Akiyoshi 'Greyhound' Chosogabe. "A further announcement will be made in the near future." PES 2009 for Wii also has the Master League mode, unlike last year's edition of the game. It's due out in Spring next year.
