So images suggest that there is some form of connectivity between the 3DS and the Wii U and we now have the reason why.
Using the Wii U function on the 3DS smash brothers game players can use the 3DS as a controller for the Wii U version of Smash Brothers. I for one find this very interesting because it makes it easier to have controllers for the game. For a large group of huge Smash Brothers fans you can save time packing controllers and just have everyone bring their 3DS. I absolutely love this idea and it could bring about the 3DS having the ability to be used as a Wii U gamepad. We can only hope.
