Nikon will have some new instant rebates for Black Friday that will include many high-end lenses (the current rebate program offers mainly low-end lenses). The savings will be similar to the rebates offered back in September. You still will have to buy a DSLR body in order to qualify. There is a very good chance the new Nikon Df will be part of the upcoming rebate program, the problem is that shipment will most likely be delayed by at least few weeks. I will publish the new Nikon Black Friday deals on November 24th (Sunday) and they will be valid till November 30th.
More Black Friday deals and current rebates can be found on this page.
