Assuming the menu happens to be accurate, not to mention that Nintendo sees it fit to be included in the final version of Super Smash Bros., chances are one will also be able to perform a character progress transfer from the Nintendo 3DS handheld over to the Wii U.
The menu allegedly reads, “Connect to a Wii U – You can exchange custom fighters or use your Nintendo 3DS as a Wii U controller”, which does not leave much wiggling room for any kind of misinterpretation. As with all rumors and speculation, it would be either confirmed or debunked by the time Super Smash Bros. is released on both the Nintendo 3DS on October 3rd. Are you stoked with this potential development?
