At least whole 2010
Intel has revealed some additional plans about new all-integrated Pineview Atom and according to information that we gathered, the new Atom should last through whole 2010. The plan is rather simple.
The new dual-core desktop Atom launches in Q4 2009, while the single-core for both desktop and netbooks should launch in Q1 2009.
Manufacturing starts in Q3 2009 for dual-core and in Q4 for single-core Atom and this all integrated platform should sell through the whole 2010. Judging from current plans the new dual and single-core should be coming in late 2010.
We can only speculate that the new Atom is going to be smaller, likely 32nm but this is something that we cannot confirm.
