If Nikon were to make an entirely, possibly mirrorless, new and larger lens mount then they could make and mount super speed lenses presently, too large for the F mount.
It is reputed that some camera makers curve their sensor(s) so that light falling from the closer rear element of the lens approaches the sensor at less of an angle. Of course such lenses must be made native to that sensor. This is one reason why some WA DSLR lens do not adapt well to mirrorless sensors.
Actually there are curved sensor prototypes that have been shown, but it's not clear that any are in production.
The curved sensor compensates for field curvature so that in theory the lens designer doesn't have to work hard to correct for that optically. How well this works with zooms and focus changes is TBD. I suspect the curved sensor is best suited to a fixed lens full frame camera since it will only have one lens on it ever.
