From Canon USA Product Advisories for Canon 5D Mark III and 1D X:
Affected Products
EOS 5D Mark III Digital SLR Camera
EOS-1D X Digital SLR Camera
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

Just installed. Fixes a lot, and then some. I don't shoot video, so I can't speak to that side of the update, nor have I mounted my 580EXII on the cam yet. But I can AF at f/8 with my 400 5.6 and 1.4x Canon TC Mk. II. And at night. And with confo beep. And with red blinkies in both One Shot and AI Focus modes. That shouldn't be possible. But it is. I am a happy camper today.
EDIT: I am not a happy camper. DPP no longer functions as an editor with 1.2.1. I have another thread about this issue in this Camera forum.
