Both these cameras are for serious shooting.
Check the video performance for yourself first, see where your needs are:
5D MkII: http://cweb.canon.jp/camera/5dmark2/index.html
5D MkIII coming soon: http://cweb.canon.jp/camera/5dmark3/index.html
More samples at youtube and previous recent threads here.
The MkII rocked the industry with its video capability, pros are shooting with it.
The MkIII is an improvement with even better image quality and extended ISO range (night video better).
Price for a new MkII now is a steal.
If your needs are covered by the MkII save some hard earned cash.
PS: The body price difference could be traded for a better lens.
