According to the press release on JoWood's Website, Austrian publishers should be releasing the Sam and Max series for Wii. It was something that had to happen, sooner or later.
When we say it had to happen we mean that Wii is a perfect console for Sam and Max's plain graphics, and the game is basically made for Wii Remote. You just have to think about those little in-game games and how they would look on Nintendo Wii. The PC version of the first season has been out there for quite a while and it is basically common sense to port it to Nintendo Wii.
According to the response that Telltale has made for Kotaku, they claim that it isn't a secret that they want to bring it to Wii, that it is something that they are actively looking into but they don't have any official news at the moment.
