Should I sell my 1DMKIII and Purchase the 5D Mark III?

** Lost focussing at f8. This is a downside as I was using my 100-400 + 1.4 fairly often. I have used live view focussing with the 5D3 but at lower light levels the miss rate increases. Overall I think the 5D3 focusses better than the 1D3. I see Canon Rumours is announcing that the 1Dx is getting a firmware update that will allow f8 AF so f8 Af may filter down to the 5D3.
