Didn't see this posted here so here goes:
Mamiya has lowered the cost of getting into medium format digital by offering is DM line of cameras at "DSLR prices". The DM22 kit, which includes a Mamiya branded 645DF, 80mm 2.8D (I am uncertain if this would be the LS version. The Mamiya website has a broken link to the page that is supposed to detail this price change) lens and a Leaf Aptus-II 5 (22 mpx) digital back, now lists for $9,995 USD (€6,995 in Europe).
You can read the whole press release here.
While this kind of devalues MFD gear, it also makes it less painful to get started in higher end photography. I will really have to save up my pennies (no one has any credit these days) to get myself one of these.
UPDATE: poking around several online Mamiya dealers, it appears that the lens is the non-LS version.
