If you are into long exposures, large format sensor may give you
less noisy images. Lens weight can add up quite quickly espeically
since you are into quality long range tele, if you decide to go the
detachable lens route, definitely go slow and be deliberate in your
lens choices, since you will be carrying them on hikes; the
proverbial straw that breaks the camel's back even if it doesn't
weigh much by itself. Some weight may be unavoidable, like
70-200F2.8L over 70-200F4L with the extra poundage, because with
F2.8L you will be able to use the 2x converter and still be able to
autofocus at effective F5.6 limit on the 10D/D60. It may be a good
idea to rely on cropping to bring you beyond 400mm because you
don't want be discourage by the weight so that you don't go out as
much. I'm keeping my Dimage 7i even after I get my 10D, simply
because of the versatility of its lens and light weight, so that I
can skip some lenses on some outings; besidesl, my wife could
always use it to replace her G1 clone. BTW, there is nothing
wrong with cheap plastic tripods; I use my cheap plastic tripod
much more than my fancy aluminum tripod with fluid level guage and
ball head becaue the former is so light that it can be used as a
monopod and walk with me. It's the result that counts, don't let
tools be a distraction. As Ansel Adams said, there's nothing worse
than a tightly focused image of an unfocused mind.

The hikes I go on I want to be able to use a DSLR to get the best
shots I can. I have been asked to sell some of those shots from my
707 and some have been published, but I felt I could do even better
with the DSLR. John Fielder is my favorite Colorado wildlife
photographer and he takes all his gear to some of these same
places, same with Art Wolf, so am willing to carry more than I have
been. Yes, its nice to have a little waterproof fanny pack for my
hikes, but I have also hand carried my cheap plastic tripod at
times for the long exposure stream shots and see pros hike with
some of their lenses to where I hike. I think I even saw John
Fielder up there once, but it was before I saw a photo of him so am
not positive.
I do want the speed for action and the isos for the indoor Denver
National Western Stock Show every January. I have to do a lot of
PS work, taking a class for that right now, and it's still not
quite what I want for quality.

Lisa,
Don't let the snobs discourage you. I have a Minolta D7i, and use
an EOS 3 for portraits where I need shallow depth of field. I have
a 10D on order, hoping to retire the EOS 3 to backup status. The
primary advantage of lens detachable DSLR is shallow DOF, and to a
lesser degree, speed during live action shooting. If you do not
have strigent requirement for these two, there is no reason to
upgrade from you 7x7 now. Aside from lack of very shallow DOF at
long range, a 35mm lens delivering optical quality comparable to
what you have on the 7x7 would be much more than the price of the
camera. For certain types of photography, deep DOF is an
advantage, and so is small and light packaging; after all, these
were the reasons 35mm won over medium format 50 years for
photojournalism despite the resolution limit imposed by the film
emulsion.
