Here are my thoughts on getting a 5DMarkII now....
I am using a 7D primarily for Adventure/Sport/Event photography. The lightning fast AF is just demanded in this work - plus crop gets me that longer effective lens length. I cant see slow AF working. Yet in the past year I have gotten much more interested in landscapes - and my work there is almost always in Manual Focus. A full-frame body is next on my shopping list for this work and a 5DMII would definitely complement the 7D. Really, I dont think I even care about AF for landscape work.
So for those reasons, I really should just go for 5DMarkII now. But I can probably wait a bit - at least to the summer - to get a 5DMIII with likely better IQ and maybe higher MP for landscape. The working plan is to acquire FF-type lenses (get a 17-40 or 16-35 to replace the EF-S 10-22 for example) and then see where we are in March after the release of the "London" 1DX.
Without the 7D, I dunno, $1999 for a 5DMII + goodies (at least the CF Card) would be mighty tempting to jump on now.
