Both. I also got Twilight Princess for both GameCube and Wii.
I'd get it first on WiiU though, which would be launch-day. The NX version if it's there sometime after. I'm not totally convinced yet NX will arrive next year already though. I do think it's fairly plausible Zelda U will also be on the next system some day, either through multiplat release or through TLoU-style remaster a year later.
