Both Zelda U and Hyrule Warriors in 2014 is doubtful, but I'm guessing the Zelda U date is wrong, they just made 2014 the place holder since they have nothing to go on.
Ok I'm still not understanding why people say this. Here are some facts:
1. Zelda U has been in development since 2010 roughly.
2. Hyrule Warriors is NOT being developed by Nintendo or, more specifically, Nintendo's internal Zelda team. This means that this takes no time, resources, or talent away from the development of Zelda U.
3. The Wii U is having one of the worst couple launch years ever and they need everything they can to boost it up this year.
Opinion: Have Hyrule Warriors and Zelda U this year, as well as Smash, Mario Kart, and all the other announced games is GOING to happen I think. I don't get why people assume that just because some other company is making a Zelda game that Nintendo just will be sitting by and waiting to release their game until a long time after the prior Zelda game comes out.
