Ok i give you what i thinking.
I will quote Anandtech article about Fermi :
http://anandtech.com/video/showdoc.aspx?i=3651&p=7
AMD launch it card before this time, what AMD is doing now : extrapolate GT300 performance and cost.Ujesh is wiling to take total blame for GT200. As manager of GeForce at the time, Ujesh admitted that he priced GT200 wrong. NVIDIA looked at RV670 (Radeon HD 3870) and extrapolated from that to predict what RV770's performance would be. Obviously, RV770 caught NVIDIA off guard and GT200 was priced much too high.
Performance? GTX285 SLI is like 30% faster than 5870 in average. GTX380 may be more like 50% to 60% faster than 5870 in average. Maybe even less.
Cost? 40% more transistors than RV870 and 384bits istead of 256bits. 600$? More?
Diltech speaks about GTX395 but in Nvidia history multigpu cards were launched very late (More than 6 months in average).
Basically AMD have 3 months to sell DX11 card with the help of Windows 7.
