According to GameTillYouDrop, GameStop has an Available Sku” listed both the Wii U and 3DS releasing on the same date in April. While the available SKU is not listed as Smash of course, that is the only game we know of right now coming out for both Wii U and 3DS in 2014.
Considering the fact that Mario Kart 8 is set to release in Spring 2014, we can assume that Smash 4 could possibly release around that time as well considering the fact that both of those games started development around the same time (near the beginning of 2012). Not to mention that this time around Sakurai will not be making a full-fledged story mode this time around and he also has Namco helping him develop the game.
Most Nintendo gamers would doubt this possibility, but I think people are severely underestimating just how quickly Sakurai and the team can get this game out. Don’t forget that all previous Smash games had almost exactly 2-year development cycles, so there’s no reason to not expect the same thing from Smash 4.
I’m not saying this is a confirmation by any means, because it isn’t. GameTillYouDrop has yet to show a picture or source of their claim, but it’s still very plausible that we could be seeing Smash 4 around April-June.by
