If FUD Zilla is right, there may not be a refresh of Intel's Atom platform until Q3 2009. The site claims the single-core Atom 230 and dual-core Atom 330 will be the only two chips available for almost another year as there isn't really any competition in this area:
We are not sure if this means that there might be a new Atom in Q4 2009 but the plan indicates that Intel plans to stick around with its very successful chips for a while.
In Q2 2009 Intel might let manufacturers to use dual cores for netbooks but this certainly won’t happen by the end of this year. Since Intel doesn’t really have any serious competition in this area they certainly don’t want to compete with itself.
We hope that there will be a chipset that might saves us from 945GC misery.
