Yeah, like all those cross-gen games that 'ankwardly transition' between generations....They mention that, like it's a concept that has barely been heard of, and like you cant optimize for better/diffrent specs.
Aside from that, I'm not convinced that it will be a cross-gen release. I expect Zelda U to drop hollydays 2016 and the NX hollydays 2017. I might be wrong of course, but I think the TLOU remaster route is more likely.
