i like what i see, it looks good and futuristic.
But :
1/ if nintendo goes for free form display it would be less expensive to have the sticks on the edge (with cutouts) instead of the middle. No thumbs hiding the screen, still allows contextual UI.
2/ Rumors are NX will be a home console first, and this controller would be way too much expensive to be bundled with a console at an affordable price.
3/ it's way too small to be comfy in adult hands, some have suggested it could be a devkit specific model or could have some detachable handles.
4/ i think NX should be able to play some mobile games and it needs a vertical screen to do so, this thing could work.
I can't make a choice, fake or not, it looks different and could bring something new to the table and that's what i expect and hope from nintendo.
