According to Canon Rumors, the 5DIII will NOT get the new AF system in the 7D as this would cannibalize 1D sales. I would prefer the 5DIII of course but I think the 5DII is only half way through its life cycle, and I can't wait that long.
As for lenses, I am stilling toying with these ideas:
Option A
17-40L, 24-70L, 70-200/F4L IS, 135L
Option B
17-40L, 24-105L, 70-200/F4L IS, 135L (But would add a 50 1.4 USM II if/when it comes out.)
Option C
17-40L, 24-105L, 70-200/F4L IS, 35L
I am leaning towards B right now.
I recently rented both a 35L and an 85LII for my 20D and ended up using the 85L more, much to my surprise, so I think a 135L on FF would be nice.
I do NEED some sort of UWA lens and I do not want to pay out the butt for the 14L nor the 16-85LII. This leaves the 17-40L as the best option. Of course I wish that Canon made a EF 17-70 F4L IS or something.
The 24-70L vs. 24-105L is the hardest debate. The former gives you better low-light performance but the latter is lighter, has IS, and has more reach. The former is also due for an upgrade shortly with a 24-70 F2.8 IS version that will devalue the non-IS version to some extent.
The 70-200 F4L I do own already. It is light weight and razor sharp. I plan on holding on to it.
