Dpreview member redcrow has a very good track record when it comes to "predicting" upcoming Samsung NX products (see previous posts here and here). Redcrow's latest comments suggest that Samsung is working on "multiple" image sensors for NX bodies that will be released next year. A new 85mm f/1.4 lens is also expected.
In another post from two months ago, redcrow mentioned that Samsung will release also a new "DSLR style" camera.
