Ricardo,
after the FW update today I am positively surprised at least with the XP1 and the 1.4/35. If this holds up also for the other lenses, then I would say that the AF difference between Fuji and OMD became minimal if noticeable anyway.
I expect notable improvements with all the primes. The kit zoom improved, but not as much from where it was, since it was faster to begin with. The big win really is % of locks vs non locks. And accuracy. When it lock, it locks (though accuracy per se before was still pretty good).
Also the OMD has some quirks with AF like the AF field size permanent change which does not work till today IMHO - at least I gave up to try. So I would say that AF is not fully perfect on both sides but became workable now also in most situations.
I will still give the nod to the Olympus in speed. It's just that the Fuji has become quite acceptable for many situations imho. I did some street life just last night to prove whether it was a notable difference (XF35 1.4) and it was.
Also the OMD focus lock is not always accurate. That was pointed out by a friend that had the EM-5 and has the FUji now, and myself, when I tried it. But to be fair the situation where it failed to lock I put it in was not easy.

PS:
BTW a bit off topic - since yesterday I am lucky owner of a K5IIs and a 18-135 - man what a great camera and pretty good lens. Just love the images (DNG) and could really not say which ones are better IQ - Fuji or K5IIs. What is now pretty perfect as well is the new AF compared to the original K5.
I think the Fuji is pretty good but more because of the lens. But the K5IIs to me will have the best IQ overall. The K5IIS has 14 bit RAW files (so better tonality unless you have the X100s which also has 14 bit raws), and the DR is still the best of APS_C. The Fuji has the advantage of being more resistant to the color moire, but to me the Pentax K-5 line is the best DSLR I have seen, and if you want a DSLR that's it.
I would like if Pentax did new K-mount ASPC primes that were faster. There's some selection but would be nice to have a 40-54 equivalent at F1.4/F1.2. That combined with the super high ISO capability of a K-5 would be quite a tour de force.
The only reason I am going to most likely sell my K-5 is simply that I am not carrying it (as small as it is for a DSLR). I really think it's the best DSLR I have ever had. I will still recommend it highly for anyone looking for a DSLR.
