Highly likely, as the top spec cards are often used to give the new range of cards credibility in terms of performance. Its always good to see that a company has the worlds fastest GPU on their frontpage when you are looking for information on their products. (obviously for those customers not in the know!)
Keplar will drive the prices of the second hand market for the current stock down more than the brand new stuff, which will be withdrawn from sale and pop up at random points for crazy discounts, just like the 480GTX's did for £200.
