The atom 330 was released in 2008. There will be no new ones. But a google search shows:
The next generation of the Atom is codenamed "Pineview" which utilizes the "Lincroft" system-on-a-chip architecture and is used in the "Pine Trail" platform. Planned to be announced Dec 21, 2009 and available Jan 4.
Please google things before posting questions like this.
