Samsung working on a 18-55mm f2.8 NX lens (or just a typo?)

A Samsung dpreview forum user has spotted this picture of a print/brochure/something that casually mentions "shot with the Samsung NX10, 18-55mm f2.8". There is no 18-55mm f2.8 NX lens at the moment :) It is possible that this is a typo, or perhaps a lens that Samsung is working on and this accidentally leaked out in the wild? As usual, only time will tell!
