Stephen Colbert, the once and future host of CBS's "The Late Show," will ascend the throne currently occupied by Dave on Tuesday, Sept. 8, CBS just announced. 

 Quickly the quotes: 

“The production office is open [at the Ed Sullivan], the premiere date is set, and we’re incredibly excited to welcome the creative and comedic genius of Stephen Colbert to CBS late night this fall,” said Nina Tassler, chairwoman, CBS Entertainment.

“I have nine months to make a show, just like a baby. So first, I should find out how you make a baby,” said Colbert.

 The September date was expected, so this isn't a jaw dropper by any means, but it does certainly affix a target date for one of the major transitions in late-night history (Letterman leaves in May.)  CBS added that "specific creative elements and producers" will be announced later -- that's intriguing because one would normally assume said "elements" would be unveiled along with the show. She told critics -- according to a tweet by the Vulture's Joe Adalian -- "that there will be some things that will be traditional and some things he wants to do differently." 

 Meanwhile, CBS -- which Monday morning is presenting to TV writers in Pasadena, California, at the TV critics' tour -- also announced that three freshman series will return next fall -- "Scorpion, "NCIS: N.O.," and "Madam Secretary."
