I waited til the actual Canon update posted and it bricked my camera WWWWTTTTFFFF!!!!!!
OK. Eye-Fi users remove the Eye-Fi card before you update. I clicked the update firmware and it went black. Turning on and off did nothing. Removing batteries, grip did nothing. Removed the CF card and nothing. The last thing to remove was the Eye-FI card and the camera booted while the power switch was set to off. Except it booted to a firmware update screen and sat there for a while not doing anything so I rebooted and it came up normal and the firmware was still reporting 1.1.3 so I started the update again and everything went fine.
