My intuition is along the lines that if AMD had a competing product earlier, then it would have kept prices down. But since Nvidia has shown what the market will pay, AMD won't be able to resist overcharging. It will probably come down a little, but nowhere near to the point of affordability.
AMD might have to charge less to break into customers that are already bought into Nvidia. There has to be a discount to cover the switching costs + still provide savings (or access).
I sure hope I'm wrong.
