Continuation on my previous post from last week: the missing lens and flash for the September 15th announcement will be a new AF-S 35mm f/1.4 lens and a new Speedlight SB-650 that will replace the current SB-600 model. This is in addition to the D7000 DSLR and the 200mm f/2 refresh. The release of the Zeiss Distagon T* 1,4/35 ZF.2 lens is probably the reason why Nikon pushed the announcement of their 35mm f/1.4 (previous rumors pointed to a 2011 release).
I will do another recap later with the details of all expected products.
