If AMD had anything ready I expect they'd be leaking it now.

AMD has to big-up the future because Atom has caught it short and AMD's recent server chip woes have made a dent in AMD's image as a smaller, smarter and more agile competitior to Intel. If AMD really did have something new in the pipeline I'd expect them to be leaking as much info as they could to try and boost their share price seeing as their recent market news hasn't been stellar. If there isn't much soon then I expect the "new" Atom-smasher will just be a Geode refresh. Maybe it's the distraction of absorbing ATi but AMD seem to be struggling to keep pace with Intel at the moment.
