The Kodak cameras are rather expensive, and they've had problems with noise
over ISO 100 and moir?.  And they're based on basic consumer level bodies,
but shoved, willy nilly, into the pro arena.  The Nikon mount version is
based on the Nikon N80, the Canon version on the Sigma SD9.  There is a
certain distrust of Sigma around here, and many feel the body may not be
rugged enough for the rough and tumble of pro use.
As far as the Fuji S3 Pro, I really have no idea why it doesn't enter into
discussions more, except possibly because of cost and that it, too, is based
on the Nikon N80.  I don't think the Linhof is widely known, or available,
in fact, it was only recently that I had even heard of it...

Quite a few people have the Fuji S2.  I like mine quite well; I bought
it when the alternative was the Nikon D100, and I'm quite happy with
my choice.  I'm not really clear that the S3 offers a lot of
improvement, though, whereas the D70 improves on the D100 in many ways
and cuts the price a lot.  

The Kodak 14n gets good reviews as a studio camera from the people
who've used it, and a lot of random hatred it sounds like from people
who haven't.  I haven't used it, but if I were looking to add a studio
camera it'd be my immediate choice.  

The main reason you don't hear these mentioned much now, I think, is
that they're *old* by the standards of digital photography.  We tend
to talk about news.

The Nikon version Kodak is probably still the "best" dSLR out there: it
would probably be my first choice for a studio digital camera. However it is
big, heavy and costs more than twice as much as consumer dSLRs. Take a look
at the "pro" Canon dSLRs in a camera store. You would not want to carry one
of those beasts around your neck under almost any circumstances. I have
never seen a good article, as opposed to much of the faith based diatribes
that appear on this newsgroup, as to why that Kodak full frame sensor has
not migrated down to consumer level cameras. The Fuji is an excellent dSLR
but on price gets beaten by Nikon in the consumer arena.

--Fujifilm's S1..3 series are aimed at Nikon lens owners, mostly pro.

--Kodak's 14 (both flavours) is simialarly aimed.

--Linhof digital?  They're not even mentioned on dpreview afaict, and I don't
think they have anything at the "35mm" scale.  So they're a bit under the radar
or probably simply OT for this NG.  Definite pro territory.
http://www.linhof.com/english/index.html look up digital there and it is a print
quality control system they show...

--All rounders:  the Nikon, Canon, Pentax, Oly, Minolta solutions are pretty
mainstream camera systems.  People are famillar with their names, their
products; many people are invested (glass/flash) and so it goes.

--The more common manufs above are accessible.  Can you get your hands on a
Linhof or even a Kodak 14 (any variant) to touch and feel it?

It would be best that their are innovative and/or bleeding edge quality
companies to keep the more gneral guys on their toes of course.

For us mere mortal$, the main OEM's will be both out main source of supply and
discussion in this NG.

As long as the discussion is an SLR digital camera or its components, it is of
course very welcome here regardless of who makes it.

Cheers,
