This is 100% rumor right now, so please take it as just that. According to Nintendo’s German general manager, the firm is looking to release two of their biggest games in the Spring: Mario Kart 8 and Super Smash Bros for Wii U.
“For next spring two more big license games are also announced for our TV console with Mario Kart 8 and Super Smash Bros.”

Thanks Ricard for the tip!
PE’s Take:
That would huge for the Wii U if both games came out in the Spring. Nintendo did this back in 2008 with Super Smash Bros Brawl and Mark Kart Wii. So this is definitely possible.
