From conversations with dealers here in the US, they've received as many as two separate D4 deliveries and are expecting another small D800 delivery before NikonUSA closes for inventory. I'm guessing that Nikon is using air delivery from Japan just as soon as there are enough units manufactured to allow a one-for-every-dealer (or more) shipment to occur. That will likely stop next week for the year-end inventory process here in the US. But before that happens, it appears that Nikon is pushing everything it can out the door, which should help its year-end financials.
Also, dealers should be getting the MB-D12 grip on Monday, so Nikon appears to have gotten all the significant parts into the chain about the same time for a change.
While the flow of new cameras and accessories is now a measurable trickle, lenses still seem to be very very tight in supply. We seem to be back to where we were before the quake: high demand not met by supply.
