After hearing the news I was completely frustrated with the annoucement until i watch Auorama talk about it and then i understand why they are delaying it. My examples are Mario Kart 8, and this years Splatoon. delaying the Zelda game to release in 2016 gives two things a system seller for 2016 around the same date those later two were mentioned . Plus,now we know NX is the next handheld, reason why Iwata is saying hardware when he talks about it. Iwata says Wii U is here to stay and with releasing Zelda in 2016 it is proof.
With titles like StarFox XenoBlade, Yoshi's Woolly WOrld, and SPLATOON beinG released this year Nintendo needed a big release for next year to keep the WIi U 's momenteum. Nintendo always knows this is a marathon not a sprint and this delay proves it. I'm excited to here this news for the future of the Wii U
