Having owned the 5DII with a 70-300 IS L lens I think its an awesome camera with few short comings.
The 6D in my opinion is not a significant upgrade. The 5D III will give you better auto-focus and a hair more low light capability.
You will see greater improvements by using better lenses than upgrading the body at this time.
I would love to keep my existing 5D MK2 but to be honest could do with replacing as it has been used in some fairly harsh environments over the past 4 years, mainly Desert and dusty conditions. I also have a nice existing selection of quality L, and Sigma lenses which cover all my current requirements..
