From what I can find via a little Googling, Sony seams to be able to sync up to 1/8000 on NEX and A7 with EFCS but some gets some shading over 1/2000 especially with non native lenses.

Yes. At very high shutter speeds where you have just a small slit moving across the frame, the difference between the way the shutter blade moves and the way its shadow moves becomes increasingly important. But fortunately, I don't think we'll have much problem with that with the E-M1 solution, where the EFCS is turned off automatically at highest flash sync speed (the highest shutter speed at which the shutter is open across the entire frame at the same time). At 1/320, the shutter-shock issue is pretty much gone so I don't see a problem with the feature being turned off at that point. On the contrary, that seems like an advantage since we don't need to remember to turn the feature on and off depending on which shutter speed we are using.
