We have a double dose of good news for 30 Rock fans today:

First, the show has started shooting new episodes, as NBC is planning a January premiere for season six.

Second, insiders confirm that Will Arnett will return some time in early 2012 as Devon Banks, one of the few men who can stand up to Jack Donaghy in the boardroom. When he's not making googly sounds to his adopted twins, that is.

Arnett stars on NBC's Up All Night and is also at the center of another exciting rumor this week: Arrested Development might return to television!!!
