This deal will come and go. Some will take advantage, then others will complain a few months from now when it's back to full price. And then price stays there for two more years. So my advice, buy one if you need one, but don't buy just because it's a "bargain." Remember back in the day when Nikon used to always put out deal flyers. Then they stopped doing it...
Will it affect used prices? Maybe temporarily, but the D700 is a totally solid camera and will most likely hang in at $1,500 to $1,700 for a long time. I still remember all the people getting madder and madder when the D700 would not drop as they wanted...
