Why m4/3 200/2.8 would be expected to be cheaper than FF 200/2.8?


If anything it requires glass to be manufactured at higher tolerances to accomodate higher pixel density of smaller sensor. 30 surfaces in case of new Pana lens. Also, new lenses (all sensor sizes) are these days designed for future higher resolution sensors in mind, at least theoretically, therefore again higher cost to manufacture which is part of rationelle behind recent expensive glass.

As pointed out, a 200mm f2.8 FF lens is a lot cheaper. So, why would you expect a MFT 200mm f2.8 to be a lot more expensive?
