Just a couple data points:

  <http://www.dpreview.com/reviews/sonydslra700/page22.asp>
Sony A700 - 100k exposures
Canon EOS 40D - 100k exposures
Nikon D300 - 150k exposures
Olympus E-3 - 150k Exposures

Canon EOS-1Ds Mark III - 300k Exposures

The PRO cameras appear to have a longer life, but not THAT much more
