While you may turn out to be correct in that nvidia may indeed release a card in November. . . the real debate (here and elsewhere) has been whether the new top-tier card will be released in November. So the release of a mid-range card isn't particularly relevant to that "debate" (and I use that word loosely).
And in that interview with Cevat Yerli, he says the card will be of "great value" something you wouldn't exactly say for a high end card.
And anyways, I talked with some Nvidia people recently and they said there were new 8800's coming out, but we all knew that already. If they do come out with a new high end though, I'd imagine they'd go with a new number unless they want to keep confusing consumers.
