I think that there were alot of people expecting to see a whole whack of 1DMKII bodies show up on ebay at firesale prices. I don't see this happening now and those that do show up there will retain alot of their value. The 1DmkIIn purchases, IMO, will be buyers moving up from the 20D and be their first 1 series body.
That's sounds reasonable. And probably I'll be one of them
