There probably is also a lobby that wants to sell memory sticks, CF cards, SD cards etc. And the iPod would erase this market, basically, since it's TERRIBLY cheap compared to those cards. So I think it might not be in the best interest of many camera makers to enable such a support.
For the user, though, it'd be great, yes...
Ceterum censeo Apple should build a stereo microphone into the iPod - or at least allow a stereo mic add-on. (The ones available are mono only.)
