The Nikon 1

In order for it to be as fast as, it would need to have cross-type PDAF (the fact that no such type sensor is listed in specs: I assume its not in there) and it would need a fast lens with AF geared for it. The only fast lens they have as of yet is the 10mm f/2.8 pancake. Focusing quickly at 10mm is not a major achievement either, and AF speed is sort of non-issue at such a wide angle, any relative measurement is almost irrelevant. I bet anything that their telephoto option: the 30-110 will not be as fast as any modern 70-200 f/2.8 (or equiv) paired with a cross type sensor, same with the 10-30 compared to a modern 24-70 f/2.8 or fixed in the range. They may claim "worlds fastest" this or that but, there is that limitation without a cross-type sensor. Just like how Olympus made the "worlds fastest af" claim even though (most) f/2.8 and faster options paired with a cross type are actually faster.

Moreover - with these cameras being geared towards more casual purpose use, does the quality of continuous AF tracking actually merit much for its category? How many times do you use AF tracking in just your casual shooting conditions?

Another caveat of Olympus' "fastest AF" is assuming it is an environment rich in contrast with a simple target, PDAF in difficult lit scenarios still exceeds the abilities of Oly's "worlds fastest AF". My A700 focuses on this white wall in front of me, by recognizing the faint and subtle texture, but the E-PM1 doesn't see that. I guess my point is, is that manufacturers make claims with a special asterisk that can only be explained and figured out when its in your friggin hands, lol. Also the point is, that the TECHNICAL numbers are absolutely limiting factors, at f/5.6, how can any lens be as fast AF as a 2.8 or faster with cross-type. Its just not going to happen.
