Seems like a typo to me, as discussed in the Smash topic. If it does happen to be true, by off-chance, then I'm interested to see what Nintendo has planned at E3 for release this year. In order to have a balanced release schedule they'd probably have to announce something for release within the next year, much like they did last year with 3D World and Tropical Freeze. There's a good chance they'll do that anyways, but Smash being delayed further increases that.
