Your right...no product...price doesn't matter. I bought my D700 in March, 2011 for $2195.00...just after the earthquake in Japan.
If I was looking at buying a D700 with old technology, or the D800 with all new technology...I'd spend the extra money.
Nikon may be dropping the price so that they can clear out inventory. Dropping the price will separate the D700 from the D800 price wise and attract buyers to the D700 as a deal. Otherwise, the D700 could just sit on the shelf as it's passed by as the D800 becomes available. The pricing at the release of the D800 was too close and not many would opt for 4 year old technology when they can get the best for only a few hundred more.
