Compared with the last one and the last last one, what is "new" actually? :-o
And, "2013 or Later"? 2013 has only three more months to go! And in 2046 which still means "Later"!
Maybe each year Ricoh could change the coating name from SMC to HD for some lenses and also the colours of some existing Pentax lenses can be changed (if not yet) and after twenty years they can still have their roadmap and lineup got updated each year, annually! What a GREAT PLAN and brilliant idea !! >:-{
