I think you'll be able to find lots of 1D IV's for around $1500-$2000 inside of a few months, if not sooner, so if the 1D4 is your dream camera, watch for deals!
Look at ebay completed listings. There are already several 1D4's that have sold for under $2K in the last few days. The average price seems to be below $2300 at this point. I'm half tempted to sell off my 1D4 while I can still get more for it than the 7DII costs but, you know, I don't know if its worth it or not. My guess though is that the 1D4 will drop quickly in the next couple of months until its about the same price, on average, as the 7DII and then the used price will trend along with that camera. At least, that's what the 1DIII was doing for a long while
