Even though they proved very powerful, they were not so significant when compared to largely less expensive Radeon HD4870. The arrived of Radeon HD480 X2 has made their loss complete.
The chipmaker tossed around by this problem will react by the end of the year with a new product called GT212. Even if architecture will not be noticably different from the GTX280, these chips will be produced in 45nm (compared to 65nm currently) what will allow a reduction of their production costs and to be able to go up much higher in frequency.
Time is likely to appear to drag for them; the media being focused on the manufacturing defects of their chips intended for
