For those who have been looking and waiting patiently, the D300s is back in stock in many stores, including B&H. The body is $1700. Just thought I'd pass this tip along since it's been so long and there may be some nikonians who have been trying to buy for months.
Adorama appears to be $100 less with a "special price" when you add to cart.

The only possible connection I can think of, with the D7000 and the D300 showing up in stock at about the same times after a fairly long drought, is that the Thailand factories production is likely getting back up to capacity again.
It is possible that the delay in the D300 replacement is due to logistical issues related to the flood recovery in Thailand.
