What fear mongering? Many people on this forum lambasted AMD for its initial high prices when it had a market monopoly, and most people understand that NV helped bring prices back down to earth.
Further, you jump to conclusions in your post. You completely ignored a major other reason why AMD could lower prices over time: TSMC 28nm process maturation + AMD's weak pro graphics card market share.
I think NV hasn't dropped prices as much because they make so much more money off their professional graphics cards. JHH of NV said they are still constrained by TSMC 28nm capacity. If you made FAR more profit from the same GK104s in your pro card segment than you did your gaming segment, faced huge demand in your pro card segment, and were capacity constrained, it'd make sense in the short term to sell all your GK104s as Tesla/Quadro cards and reserve zero GK104s for gamers. But NV knows it can't just abandon gamers and market share like that. So it appears NV is willing to sell some GK104s at relatively low prices to gamers, but is in no hurry to drop prices on GK104 because they can't make it up in volume due to capacity constraints.
There is more leeway to drop prices on GTX 670/660Ti as those are harvested chips so one would expect more price drops by NV there. However, as TSMC 28nm process improves, there may be less harvested chips to go around which would counteract that.
