As the step-wise price/performance curve on high-end DSLRs shift hits a downward step, so must the price/performance curves for the MF players. It will also only get worse/better (depending if you're a buyer or seller I guess) - especially if we see the S2 MF form factor copied by other players, which we undoubtedly will.
I think the pricing paradigm, model/sensor churn (and feature-creep) that has become the hallmark of the DSLR world has now moved upstream. Never thought I'd see the day where a clean (I assume) H3D (Mk1)-39 kit for < $13,000 like has been listed on FM would sit there for as long as it has collecting drool.
As for the lenses (ah, wait until the S lenses are priced...), look at Canon, Nikon, etc. The lens prices stay relatively stable as the body prices 'plunge' with every cycle - but you do, sometimes, maybe, well, occasionally, get more lens performance for the same $$ (more so with the new Nikon WA zoom offerings). No reason Hassy or anyone else need be any different.
As Mark states above - give'em a little taste, watch their eyes go wide and their wallets come out and suddenly they need a REALLY compelling case to get them to eat the $$$s in glass, etc to pull a switch.
That said, such downward price spikes are also a good way to remind your competitors who one of the big elephants in the room is (and who isn't) -- if you have the pockets for it.
