wouldn't all the tech demos have been built in small spaces?
And why would you ever not want max graphics possible?
if everyone did, every Wii U game especially 3rd party ports would look incredible and immaculate. The only Wii U 1st party game I've seen not do as much as I knew it could do is Pikmin 3 in my minds eye. But i felt as it started its life on the Wii and they were getting used to how different HD was I can forgive it.
You can already see the progression on SM3DW and even from there to Mario Kart 8 and Smash Bros, I can't wait to see what they've been able to do with Zelda U
Especially when they had ages to experiment, so much that they decided to build Wind Waker HD which indicates that the Zelda team are definitely ready to max out the graphics and by the sound of it give us some really unique gamepad and online gameplay
