There is, however, a very damning video by DigitalRev demonstrating that the X-E1 completely failing to get an AF lock on a moving subject in low light. Presumably the X-M1/A1 do better, both being newer cameras, but how much better is an unknown.
Oh man, that video was from before firmware 2.0. How things have changed...
