  I suspect larger viewfinders are perfectly possible within the
  current prism dimensions (the prism does not magnify per se).
  However the higher the magnification the less bright is the
  resulting image in the viewfinder. The total amount of light
  entering an APS sized SLR is less than half the light a full frame
  SLR gets. The difference must be compensated somehow by smaller
  viewfinders but comparable in brightness. Even so I think the
  manufacturers have more stringent demands in optimizing light path
  to minimize light loss in an APS DSLR - and this could contribute
  significantly to the price.
