I don't think it'll cost 1000. AMD doesn't have the reputation anymore to sell at those prices. Maybe competing with the lower 6-core intel processors.
If (and only if) they come out with something genuinely competitive with Intel's Extreme Edition (and I don't mean the 980x either - I mean whatever is coming out next year, around the same time frame as Bulldozer), then they could justifiably charge $800+ for it, as they have in the past. It has little to do with reputation, and much to do with performance.
