I asked the same question just the other day.
http://forums.dpreview.com/forums/thread/3387499
They received mine on the 15th and it's now in the shop being worked on; not sure how long it will take at this point.
Thanks for the info. Looks like anywhere from 2-6 weeks. Been shooting the D7000 as a backup. Not a big wide angle guy, so no big deal.
In fact I'm thinking about selling the D800 once it's repaired and pick up a D7100, as I mostly shoot with a 70-200mm VRII or a 400mm f/2.8 VR, and don't mind the crop factor.

SN 30175XX Received late June from Amazon. I've held off sending it in, for one, because I wanted to make sure there was a definitive fix, but also because I don't generally use the outer focus areas. But now I'm thinking about selling the camera, and don't want to stick someone else with the problem.

My D800E should have a frequent-flyer account. It has been in for service (left AF problem) three times: twice to El Segundo, then to Melville. I just got it back, and this last trip was a quick turn-around: only 9 days total.
But the damn thing still shows obvious AF errors. The service receipts don't tell much about what was done. There are codes (B1, B2, et.) and sometimes a note that focus or mirror was adjusted. For early production cameras that had the bad calibration data entered for individual sensors, global adjustments to the AF baseline value, or tweaks to the mirror stops, will not fix the problem. Thom Hogan reports that Nikon now has a procedure for recalibrating the firmware tables that store calibration data for individual sensors. This is the fix that is supposed to work. But it is apparently a long process (maybe one hour), and Nikon probably does it only as a last resort. I don't know if they have tried it on my D800E.
Anyway, mine is on its way back to Melville, for the fourth try, along with a note demanding a replacement camera if they can't fix this one (s/n 3001xxx).

I sent mine on Feb 8th to Melville via UPS ground and received it yesterday (Feb. 25th).
A brief test indicates that the fix is effective. Now the viewfinder AF with the leftmost point matches manual and liveview focusing; results from the left and right AF points are comparable; and using the center point produces the sharpest image. Tested with a 50mm af-d at f1.8.

Well, I just got my D800 back from Nikon and upon initial inspection and after a few test shots it looks like the AF is fixed. I had to make some fine adjustments for the lens but so far I'm pretty happy with the results and with the folks in Melville. The turn around time was reasonable, even though it was tough being without my camera for a month, but I'm happy to have it back.
Now it's time to burn a few more dollars on lenses before the rebate ends.
Just an FYI
1. Thom Hogan reports: "If your camera was fixed for the left sensor problem I've been writing about, you'll see an item labeled Repair SC 201759."
I have this listed on my repair invoice.

Ever think to ask Nikon directly? Given they have your camera and they're the ones handling it, what makes you think your going to get an accurate answer from these forums? Seems like all you did is waste everyones time who read this.

I can’t tell you how overjoyed I am that I wasted your time since it doesn’t see you have anything constructive to do with it that doesn’t require a moist towel.

Thom's information is usually reliable, but I'm not sure how much faith to have in the above statement.
If you google for "SC 201759" you will find that this code has been on repair receipts since at least as far back as 2005, and for services on D70, D2H, and other cameras.
This suggests that the repair code is not specific to the D800 left AF problem. But perhaps the code refers to a procedure that is part of what is necessary for a fix to that problem.
Thom also reports that, for those D800 units which were miscalibrated during manufacture, the correct repair involves recalibrating individual AF points, and storing the data into tables in the camera's non-volatile RAM. But in the communications that I have had with Nikon support reps (about my own D800E with left AF errors) they do not acknowledge that such a procedure exists. I don't know if it is possible to find out if this procedure has been performed on a D800(E) that has been in for service, or if it is related to the "SC 201759". It's also possible that some cameras do get the correct fix, but do not show the "SC 201759" code on the receipt. Perhaps the techs don't always enter that info on the receipts.

I would not put much faith in Thom's statement either. I just received my 14-24 and D800 back from Nikon. Nikon repaired the lens for a drop but is showed severe back focus on my D800, so I sent the lens back together with the D800. Haven't tested it now for the second time yet. Both the service order for the lens and also the D800 (different invoices) show: "Repair SC 201759". It probably just means focus repair/adjustment and not any specific procedure.

Received by Nikon on Feb 26th. Showed up on my doorstep today...That's 7 business days...not bad at all.
Testing with my LensAlign tool shows symmetrical focus on left and right, and nearly dead on without any AF fine tune adjustment. Perhaps 1-2mm front focus at 3 meters.
I am happy to get the camera back, and although the AF issue really didn't effect my style of shooting, it's nice to know I have a fully functioning camera if I plan to sell it.
