AFAIK, the 8-15mm was announced at $1499 and it's retailing at $1499
It was announced at $1399 and during the very long wait between announcement and delivery the price went up. I have to give Adorama kudos - for those of us who ordered early, they held the $1399 price.
The MkIV could go on to become a very sought after body if it does become the last 1.3.
In that scenario, I don't see myself selling my MkIV.
At least not until they become collector's items and sell for enough to let me buy the new 200-400. 
Actually, I think I could be very happy with two MkIVs...
Finding a new second one may become a challenge soon. With 5-6 months until the "X" comes out, I wonder how much production capacity, if any, Canon will use for the MkIVs.
I see Adorama has MkIV's in stock, but at the current price of $5,499, the price delta between it and the 1D-X has come down to $1300.


Do you have access to the 1D X?
