Nintendo's Cammie Dunaway has just confirmed that a new Mario game is coming to the Wii.
At Nintendo's E3 conference - which is taking place as we type - she said this:
The number four is the key to Mario's next surprise. For the last 15 years, Mr Miyamoto has been thinking about one new way to let you play a Mario game that's never been possible before. Today here's his answer - New Super Mario Brothers for Wii.
The game will have a multiplayer focus, with four players being able to join the action at any given time and compete to reach the end of the level. It sounds a bit like Smash Bros to be honest.
The game will launch before the end of the year.
We're reporting this news as it happens - expect more details, including images, later.
