IMO:
1.) Current Dx10 games are just Dx9 ports, or patches. Their extra
functionality was already/also available in Dx9. See Crysis: the Dx10-only
Very high settings could be unlocked with a hack, and it was running on
Dx9 hardware.
2.) Dx9 has not reached it's limits yet. Again Crysis: it has the best
graphics right now, and it runs on Dx9.
Dx9 has been around for some time now; but HDR only became popular
around 2006, when there was strong enough hardware for it. But the
much older, pre-Dx9 Morrowind already had similar (subtler and less
sophisticated) HDR-like effects! So probably the effects that currently
make dx10 "more" (like better fog, lightrays, etc.) could also be
implemented in Dx9.

So I sort of agree with Valve. Dx9 is not dead yet. Making games
natively/exclusively Dx10 would also mean that people will have to
change to Dx10 hw and Vista if they haven't done so up till now.
