Perhaps what is not being thought about is that MF guys are already
taking a hit on the long end.  The 645/67 400mm is really much closer
to a 200mm in 35mm format.  So they could do the mental jump and say
that now their lenses match the 35mm because of the same sensor size.

JCO is correct that there would be NO difference.  If you are thinking
as a MF only kind of person, you would think that your lenses suddenly
got longer (almost 2 times).  But they would be no different than a
full frame 35mm DSLR.  Just bigger and heavier.

One other aspect that no one has mentioned is that MF guys usually are
not shooters of long glass.  They are shooting wides, normals and short tele's.
They may not be very excited to suddenly lose their wides.  My thought
is that they would be much less excited about the change in focal
length than the 35mm guys.  I know I would have.  Having big, heavy
55, 75, 90 lenses that are very unremarkable, not to mention relatively
slow by 35mm standards, just doesn't seem like a great improvement
over shooting a full frame 1DS.
