So, you used an advertisement from a company whose bottom line is the Yen to prove a scientific hypothesis.  Canon is either ignorant here, or dishonest.  Did you even try what I suggested in the post you replied to:

The bigger the pixels, the bigger the effect of motion blur.  The thing your model ignores is the fact that when a point of light does cross into the next pixel, the bigger pixel puts the effect of the blur farther from the actual blur.

You identify it less as motion blur with the bigger pixels, but regardless of what you can identify, the total blur is greater with bigger pixels (lower pixel density).

It's easy enough to simulate this in an image-processing program.  Take a small sharp image crop, and apply a motion blur of about 3-4 pixels at an arbitrary angle.  Now, make 4 copies and pixelate them at 2x2, 3x3, 4x4, and 5x5. Which is the blurriest?  Which is clearest?

High pixel density cameras such as D800 does need to use better technique such as on tripod and use best lenses in order to fully leverage high pixel density potential.  Sure it doesn't have more blurs than a 22mp camera at the same export size but then you'd waste its 36mp potential.

Meanwhile my larger-pixel 1DIII (10mp) and 5D Classic (12.8mp) are fully capable of generating very sharp photos when view at 100% cropped or per-pixel level or to print to 19x13" or even 26x18" sizes.

Blurry?    1DIII + Canon 100/2.8 macro (non-IS version) hand-held .

Or two 100% cropped airplanes snap-shot from a 10mp camera, blurry?
