This is the email I got from a Best Buy employee as a response to the Best Buy: Nikon D300 discontinued by the manufacturer? post:
"Checked the inventory system at work. It is a "deleted item" now. For what it's worth, the D200 is as well. Doesn't mean we will stop selling it, just stop buying it from Nikon, that's all. Typically, stores that still have them, like mine, won't get anymore. The ones that Best Buy has already purchased long ago and still receiving will just be shipped to stores that sell higher grade cameras. My store primarily focuses on D40 - D90 because we are in a much smaller market."
