Nikon's existing DSLR+lens rebates appear to have been extended through the 24th of September or through the end of the month. I've gotten conflicting information from different dealers. The dealer I trust most tells me that he thinks it's only the D3100 related rebates that expire on September 24th and the rest extend to the end of the month. That's an interesting date, since we expect new equipment to be introduced on the 21st. One would guess that if the new mirrorless system is being introduced, that it'll slot under the D3100 in price, thus keeping the D3100 price down via rebate will probably end for at least a short period to create some pricing differential.
