You're gonna have to wait, at the *very* least, until the next-gen cards are actually available.  And I'm not expecting much movement until the 6800NU (supposed retail price: $299) hits the street, which could be several months from now.  Introducing a $500 card won't do much except maybe push the prices of today's super-high-end parts down a bit; it's certainly not going to have much pricing impact on anything already in the $200 range.
