Actually D700 at that time was sold for around $3500 street price. Which IMHO still ok, but RRP was $3888. If given the same calculation, D800 street price should be around $4100.. which to me too much. If at street $3500.. can still consider.
remember that the first few days when D700 was released, it was also selling at RRP... Just wait for the mad rush is over, and see what happens when the dust settles.
