I stumbled over a report done about a Canon 1D X presentation.
http://www.nikonuser.info/fotoforum/viewtopic.php?f=35&t=1481&sid=fc1b93b823dc0fcd687f64f4f2003688and tried to make sense about this slide shown during this show:

Motion blur
*Thanks to larger pixel size motion blur will be reduced compared to EOS-1Ds Mark III.
*What is motion blur?
* Shorter shutter time are (sic!) needed to freeze moving objects. Pixel size has an influence on that.
* Smaller Pixels are requiring a shorter shutter time for sharp pictures without motion blur.
- A graphic showing the point (sorry for the pun)
(I think "shutter time" should be translated to "exposure time". And the first word of the last sentence is spelled wrong. There is no such word as "nothinger" or "noer" known to me and if: It doesn't make sense here.)

I thought "Hä?" which can be translated to "WTF?". What does this graphic show? I think they refer to the gapless lens introduced with 1D X. What is not shown is pixel pitch and without this the slide is meaningless. The concept transported in the slide is misleading.
Am I missing something, is there a correlation between pixel size and motion blur?
Thought experiment: I paint a grid (with width of the lines = x) onto the screen and watch a movie of a car race. Now I reduce the width of the lines. I cannot see any improvement concerning motion blur, I suppose.
Maybe someone is able to make sense out of it and explain it to me. I will try to understand, I promise!
