It's the holiday buying rush and prices are adjusted to aid in that. Nikon always seems to have some sort of deal, but if I look back to my experience buying the D600 and D800 towards the end of last year I never saw a deal better than the one I got/could have had in December. Best you can hope to do by waiting is for someone to match it. The D7100 will stay where it is until they replace it, and then you might as well ask if you should get it or the new model. If you're ready and there's a price break, buy!! Better to start shooting now than have to wait and wish you had it while the price is up.
