It is way too early to tell. We do not know much about the internal goals of that tech-demo (beyond of course it was meant to show the power of Wii U and they used original Twilight Princess assets). We do not know the technology behind it. we do not know if the next Zelda game will be based on it. It could be the Wind Waker engine (which was modified for Twilight Princess and later upgraded for Wii U in order to run WWHD) in which case I believe the final game will look slightly better considering that engine was upgraded for WWHD and it runs a lot more smoothly than the tech-demo.
