I'ld stick with the 5D now. If I were to get the Mk2, I will need to spend not just on the body, but on:
a) Grip, ridiculously priced at $500 and currently out of stock actually it's $390-$395
b) Batteries, again ridiculously priced and probably no OEM alternatives for now since it's quite new got oem but need separate charge which may not be reliable
c) Memory cards, probably need another two 8 or 16GB cards on top of my two 4GB cardsonly if you shoot raw, if jpeg, 2x4gb is more than enuff for a days shoot
d) RAM upgrade for my computer to handle the larger files ram price very cheap now:bsmilie:
More importantly, I can leave without the additional MP, dust cleaning, high ISO etc.
