Many people try to mix up the retail price and the street price.
I doubt Canon will drop the retail price of 5D3 to under $3,000, let alone to $2,799. I don't keep all the records, but I don't think Canon drops the price right away. They will just have their rebate promotion, just like now $200 for 5D3. Then, the price becomes permanent. So, I think the first price reduction for 5D3 will be $3,299 or $3,199 at best. Also, the retail price of 5D2 didn't drop dramatically until this year.
Now, let's look at street price. If anyone recalls, exactly a year ago, if you can find a new 5D2 at $2,200, it's a good deal. There were some Black Friday deal for $1,999, but it came and went really fast. In the used market, used 5D2 was around $2,100. While a used kit with 24-105L was running around $2,900-$3,000 and with 24-70L at $3,400-$3,500.
This year, I think it's quite out of characteristic that you can find a brand new 5D3 for $2,700-$2,900 for a Canon camera that is retailed at $3,499. Thinking you will get a new 5D3 this winter for $2,500 is kinda a stretch.
I truly believe that the MAP policy has something to do with the availability of the new 6D. Canon forces retailers to advertise at a minimum prices. If you can find a new 5D3 at $2,500 or even $2,800, who will buy a 6D for $2,099? Don't hold your breath for anything under $2,750. If you can find one for $2,750-$2,900 and you really want it, I'd suggest you to grab it.
