Short of anyone here working at Nintendo, we have no insight into what the bar is for release, the LOE to fix graphical bugs, or any of the challenges they face between platforms.
If this were the actual reason, Ocarina of Time would not have released on it with so many graphical glitches and input lag which they eventually fixed later.
