In my waiting for the lens, one thing does come into question - if the new 5d3 software will correct so much of the known problems of the lenses - what's the point in spending 100% more on a new 24-70 in place of the much cheaper 24-105 or even a lessor non-L lens?
These are two very different lens. The point is if you need a faster lens (I do!), the 24-105 while it has IS may not suit you. In terms of sharpness, the new 24-70 II promise to be very sharp, maybe even as sharp as some of Canon best prime (according to the published MTF charts). I personally find the 24-105 (all three copies I have tried) not sharp enought and while I do need a zoom, I continue to use my prime in that range until I find a sharp enought zoom.
The 5d3 software will not make your lens sharper then they are, or faster then they are! No matter what is inside the 5d3, putting better glass in front will provide better result!
