B&H has the new Canon EOS 1D Mark IIN listed for $3999, but it is "out of stock" when I checked this morning. The main difference with the 1D Mark II is the larger LCD screen on the back and a faster buffer.
Meanwhile, it appears that various stores are clearing out the Canon EOS 1D Mark II, so if you want this tried and true photojournalist's camera, now might be the time. B&H has it for $3829 and Costco.com has it for $3799. The advantage of buying it from Costco is the fantastic warrantee that Costco provides on its products. Although I might say that for only a $200 difference on a $4000 product, why not get the (very slightly) updated version? DPReview.com has more on the 1D Mark IIn.
In other news, Canon is offering (its now traditional) fall rebates on selected Canon EOS products bought from authorized dealers (i.e., not Abes of Maine and Costco.com). The interesting twist is that if you buy two qualifying products, the rebate amount doubles, and three it triples. Here are the qualifying products:

Do you mean you can't buy everwhere to get that rebate in the States? Here in Europe this doesn't seem to matter...
Only authorized dealers in the USA can offer the rebate. This is to help maintain the price monopoly. If a dealer sells too much below the advertised price, they can get de-authorized. Or if they are seling "grey market" goods, they also can't offer the rebate.
