Well not necessarily. Let's consider the shutter first. Any full frame shutter is going to have to cover a greater distance in the same time compared with an APS-C shutter. For a vertical travelling shutter the distance for FF is approx 24mm compared with a Rebel's 14.8mm - in other words a 63% increase in distance. So it's really not surprising that the flash sync is slower since the acceleration and speed of travel of the shutter blades for FF require considerably more engineering. And when you actually compare 1/180s with 1/250s for X sync it's really quite a minor difference and not one which would have any practical impact for most photographers.

There's no engineering problem for Canon though. The 5DII already had 1/200 X sync. The 1DX has 1/250 X sync. 1/180 on the 6D is really going backwards for Canon.

Sigh, even my old 1D3 has 1/300 X-Sync as in 1D4.  I guess smaller sensor size therefore smaller mirror, easier to implement faster X-Sync?
