The slides made me think 6970 will be slightly slower than 580. I think it will be priced at $400. Yeah, that was the price for the smaller-GPU, 1GB RAM 5870, but then AMD had no competition.

If that's the case, GTX 580 prices will probably drop like $50. Whenever 570 comes out it will probably be between 6950 and 6970 (just like 5850-570-5870) and will be priced $3xx.
