NewEgg lists release dates for Super Smash Bros. Wii U/3DS

NewEgg has put up tentative release dates of the next Super Smash Bros. games on their website. They have a listed release date of May 14, 2014 for the 3DS game, while the Wii U game, which they apparently have no idea on, has a listed release date of December 31, 2014. Again, these are not confirmed release dates, although we may hear the release dates at the VGX Awards this Saturday.

I'm sure they'll be released simultaneously, whatever the date is.  I don't see why Nintendo wouldn't release them at the same time.
