To accommodate the Core i7 990X, the 980X must drop in price. However, this price drop hasn't really shown in e-tail, yet, but the price is expected to stabilize at around $900-$950. It is the Core i7 970 which undergoes a massive cut from $880 to $583, making Intel six-core CPUs that much more affordable. (relatively)
The 3.2 GHz Core i7 960, which is a quad-core CPU, drops from $583 to a much more affordable $294. Of course, it is no match for the similarly priced Core i7 2600, except you can't really get a motherboard to use it with.
