Details
Depending upon the shooting conditions, it may take slightly longer for the EOS 5D Mark III and EOS-1D X digital SLR cameras to acquire focus when using the Speedlite's AF Assist Beam, compared with that of the EOS 5D Mark II and EOS-1D Mark IV digital SLR cameras using the Speedlite's AF Assist Beam.

We are developing a solution to enhance the focusing feature for the EOS 5D Mark III and EOS-1D X and plan to release a firmware update based on following estimated schedule:

EOS 5D Mark III: (estimated) Late April, 2013
EOS-1D X: (estimated) Late May, 2013

Good news that Canon acknowledges the problem (no, the people who reported this obviously were not paranoid) and even promises to fix it - though we still have to see how the fix turns out and if it's the same on 1dx/5d3 (remember the af servo indicator...).

And imho still underwhelming for Canon to take a year for this while they marketed the 5d3 as ideal for shooting in just the problematic the circumstances, but better late than never :-o

Things have really changed since I started this post a few months ago.  I was very frustrated at the time and not I couldn't be more satisfied.  I just used both of my 5D3s at a wedding last Saturday and they both have the firmware update.  I shot 2,700 pictures with at least 1000 being in a very dark fast moving reception and I nailed just about every shot I took.  There is a huge difference in the focus speed with the AF assist beam now.  It once caused the focus to slow way down and now it speeds it up drastically.  My 50mm 1.2 used to say in my bag because it would simply not focus in the dark.  I used the heck out of it and shot at 1.2 most of the time with most being keepers.  When I use the 24-70 f/2.8L II, I feel like I am cheating because it focuses on whatever I want instantly.  I am very happy!

good to hear....i haven't done the update yet and have been waiting to see if anybody was having problems after updating....sounds like you're saying "go ahead and update" right?

digital paradise:
I have not heard of any. Regarding this post I have yet to read a negative remark. The AF assist beam is much improved now.
