According to the recently published information only 3 percent of all shipped processors in Q1 2010 was made with 65nm technology. Apparently Intel is moving toward shutting down the making of all 65nm processors in Q3 2010, simply due to lack of demand.
This would mean that most of 65nm processors will disappear from stores by the end of 2010 as the stock dries out. In Q4 2010 Intel expects 35% of all its processors to be made with 32nm technology.
