Green Day return to the studio?

Accordng to the Green Day fan site Green Day Authority, the band is about to return to the studio to record a follow up to the massively successful "American Idiot".

The site posted this message:

"We got an update this week from Green Day's manager about what the band is up to now. He let us know that Green Day will be going back to the studio in January, and that we should look forward to a new greenday.com and perhaps some new photos around that time.

He mentioned that the band was going to begin stepping away from all American Idiot themes, and that the new site wasn't going to be themed around the new album. I asked about the progress of the new album, and it didn't sound like we should expect anything too soon. Lets hope we'll get a full update about what kind of stuff they're working on early next year."
