X-E1/X-1 Pro with on-chip phase detection AF

No, it has no significance at all, but that is not the low-light focusing we are talking about.

So far, there is little information on this. DP Review said on the autofocus: "even in the relatively low light of a CES meeting room, [it] works very well and delivers noticeably faster and more positive focus (quickly moving into focus with minor or unnoticeable jitter) than we're used to from the X100"

That sounds hopeful, but we will have to wait for the results of more thorough testing.

There is also the fact that, if forced to fall back on manual focus in low light conditions, the X100s makes that significantly easier.
