The OP referred to an upcoming firmware update. This is exactly the kind of feature firmware updates typically provide.Surely the real question is why Leica would spend the money to do this. -- -- To ask for an 'upgrade' (which, apparently, not everyone agrees is an upgrade), for no money, on a discontinued camera, is optimistic.
Why would they spend the money? Because it's smart marketing. This is the kind of marketing that sells cameras to people like me.
