XF1 Deal Breaker (for me)

I noted that a local Best Buy received the black XF1 in stock, so I made a trip to take a look today.  The camera looks and feels very nice, better than most others in the $500 category.  I have an X100 in the collection, and the fit and finish are comparable.  The lens extension/lock mechanism is very usable, no issues there.  Now for my concern.

I tried some simple panning motions and the screen could not keep up with even a moderate panning rate.  When side-by-side compared with the S100 and RX100, the screen turns to a blur until you stop, then snaps to an in-focus image.  The autofocus is very quick once you have stopped motion, but I could see where there would be a real difference with action and with motion video recording.

Is this a shared observation, or was the camera in a non-standard mode?
