The magazines have been comparing cameras in various ways,
but in terms of "class" of camera, how would they rank?

This is my impression as to how this works:
(Models need not be in production here, just readily available in some
form, new or used)

Class 1. Canon 1DS MKII
Canon 1D MKII(N)
Canon 5D
Nikon D2X
Nikon D2Hs
Leica Modular R (Digital)
Olympus E-1
Fuji S3

Class 2. Canon 20D(A)
Nikon D100
Minolta 7D
Sigma SD10

Class 3. Nikon D70(s)
Olympus E-300
Pentax *ist DS

Class 4. Canon Rebel XT
Nikon D50
Minolta 5D
Pentax *ist DL
