Best guess: lens - $2300 plus body $3600 less kit discount $300 = $5600
And I won't be buying it. In fact feeling very fortunate to score a MkII body for under $2K with $600 of bundled software that I actually use. Best street price for the software is probably only about $300, but that means I'm right under $1700 for a new MkII body with full warranty.
Why $3600 for the MkIII body? Based on the new 24-70 pricing and the rationale that Canon is refusing to eat the currency exchange any longer but still brings it to the US cheaper than the EU. My guess is that if I'm wrong it will actually be higher than $3600.
