Can anyone confirm if it has a noticeable increase in hit rate over...say...the E-P5. if not I might just wait for the E-M1 II to come down in price a bit more.

It is little difficult to say if you get like a 90% focus rate with E-P5 for a cycling kids toward you, that how much better you want to get "much better"?

Like a scenario, you have a kids cycling toward you at 50 m range back and worth so you start at 50m range and stop at about 5m range as 40mm is too narrow at then.  If you get with E-P5 and its 5 FPS for C-AF about 30 frames from what 4 frames is slightly out of focus at closest range, then how much it really is better to have like only 2 frames out of focus or just 1 slightly out of focus?

But that is hardest test really for any C-AF system as the subject is coming directly toward and closure speed ratio increases quickly. The other challenge for C-AF prediction capabilities is target that speed varies so it accelerate, decelerate and can even stop.
