I think its just part of the natural progression of DSLR bodies. If anything the 1D4 is holding its value way higher than its recent predecessors 1D2N, 1D3, due to the fact that Canon eliminated the $4,500 category and brought a replacement that cost $2K more. That has kept a lot of people shooting with the 1D4, held its price high, and prompted a lot of people to probably look hard at the 5D3. When I sold my 1D3 to upgrade, I was not able to justify the jump to a 1DX, but looked solidly at both the 5D3 and a used 1D4. My opinion is had the 1D4 been replaced by a 1.3 crop body at the $4500 price, we'd see 1D4 used prices of $2200-2500 now instead of $2900-3300. They may actually just stay there unless the 7D follow-on does something magical to fill the void. I'm kind of hoping Canon takes the 1D4 guts and puts it in a 5D3 body and calls it a 3D for around $3500, with a street price of about $3K.
