Dont think it can be zen, as Zelda is shipping for both WiiU, and NX. Since Wii-U has a IBM's powerPC cpu, it must be compatible going forward, so NX is probably the same with a much beefier gpu. Then again, maybe theres some funky emulation going on to play all Wii-U stuff.
It would be interesting though if they used 14nm gpu in there.
