We’ve got to the point where a full-frame DSLR could carry a 40mp sensor;the 36mp sensor in the Nikon D800E outperforms the sensor in the Pentax 645D inmost regards and is only a tad short on actual pixels.

For this statement, yes, you sound a bit crazy : the difference btw 645D sensor and 35mm is roughly the same as btw 35mm and APS-C regarding
size.
One of the actual and measurable consequence besides bokeh and global light capability, is that you get at best in file resolution at lower than f/8 with D800, compared to lower than f/13 with 645D.
This said, the commercial birth-day of a CMOS 33x44mm sensor has not happened, yet.
