In the US, D300's should be headed to dealers on the 21st, meaning that a few lucky folk will have a happy Black Friday (another vague reference I need to explain to International users: the first shopping day after the US Thanksgiving holiday is referred to as Black Friday because it's considered to be the day that the average retail businesses' profits go from the red to the black for the year; it's also typically one of the highest volume retail shopping days in the US). The D3 should follow a week later. I expect both to sell out in the first shipments, so if you're not already on a wait list, you may be waiting a long time for a camera.
First US shipments won't actually have Capture NX in the box, only the registration number you'll need to enter after you download the trial version from the NikonUSA Web site. This should change with subsequent shipments so that the CD will be in the box.
The 24-70mm f/2.8G AF-S lens is already shipping in the US, and the 14-24mm should be available shortly.
