Super Smash Brothers 2014 Spring Release Was A Mistake

Nintendo Online has reported that the 2014 spring release of Super Smash Brothers was actually a mistake. There actually hasn't been a set release date for the game.
"As we were told today, the statement about the spring release for Super Smash. Bros. was a mistake. Therefore no actual date has been set except for the year 2014. Mario Kart 8 will still be released in spring 2014."
