My thoughts exactly on 5D MKII vs MKIII.
I have heard it will be continued for a while due to MKIII being more the D800.
But I would not wait and did pick up a Canon Refurb for $1750 with 400 clicks.
Thats half the MK III price and since I dont do action sports types - no way I will do a MKIII {not untill the MKIV anyway}. The CLP makes it 20% less.
Your best deals are always the older model and I think the faster and better AF is more Canon marketing hype than actual. Unless you can quote exact data in seconds to focus and # of OOF images with exact same settings lenes ... you really dont know.

The MkII is an excellent camera and I did what El Pic described, I picked up a refurb camera from Canon as my second MkII, the 'just-in-case' body. With Nikon out there with a 36mp camera, Canon can't be too far behind; it may be until next year that they announce, but in the meantime I have the security and use of a second camera at a decent price.
