It's out and available. I just installed ImageBrowser EX. I figured they'd hold off until the 5DIII release.

The software only allows you to manage 10k images, odd. I may need to change my folder structure. Right now it's as follows:
Code:
Photographs
>2008
>>01-January
>>>5 (contains JPG)
>>>>RAW
>>>>DNG
>>>20 (contains JPG
>>>>RAW
>>>>DNG
>2012
Anyways, I'm trying to get IBEX to work, right now it continues to crash, I believe I need to reboot. I will check back later with more on my thoughts.
