F/2,8 Zooms are capable to use double cross points, so why do you have any doubts?!

I would like to have both....

I have been comparing both for over two years now, both in daily real world use and also by performing specific tests...

On a 7D and a 40D, the 70-200 f/2.8 IS II does not have any low light auto-focus advantage over the f/4 IS.
