I've temporarily removed the Exotic Telephoto Lens from my Waiting For Nikon list (bottom left column). In the last two weeks NikonUSA seems to have supplied even the 600mm f/4 to outstanding dealer orders, and if you look hard enough (e.g. beyond B&H) you can find pretty much all of the exotics in stock somewhere in the US at the moment, albeit in low quantities that probably won't last long. We'll see soon enough if the resupply Nikon just did is a one-time thing or not. I suspect one-time, but I'll give them credit for now, at least until we run out again.
