Are Digital Cameras Price Exhorbitant?

The D4 is more expensive in pure dollars than the D2H was at its introduction, but it's much more of camera, even with a $1000 increase, than the D2H.  It's a question of price vs. value.  I admit, even the E5 is too much for me at this time, and the features and benefits that make up the price difference might not be enough for me.  The Pentax K30, for example, has weather sealing, a smaller body, a larger sensor than the E5, and is about half the price for the body.  It lacks the E5's faster max shutter speed (1/8000 vs. 1/6000), articulated screen, and of course it would mean switching my lens.  I don't have any SHG lens, so the switch won't hurt as much, if that is where I want to go.
