Hijacking this bit of news from the people over at Engadget. Just when you thought the Nintendo Wii couldn't have enough controllers, both 1st and 3rd party, Nintendo throws another one at us. that's right, you are looking at a "pro" version of the Classic controller. The extra shoulder controllers and the larger size of it is what designates it as a "pro" model.
I'll be honest, I think it's pretty cool to have if you are like me, somebody who doesn't have the original Classic controller, who enjoys buying the classic games and who in a sense collects video game merchandise. If you are not in that category, chances are the controller will be like many of the other Wii peripherals, bought by many, played by few.
