MTV - Adam Rosenberg was the first to pick this up over the weekend while covering the press conference for “The Swich”.

“Yeah, actually, there’s a real good part for her in the ‘Arrested Development’ movie,” he said. “There’s no offers on this one. She’s gonna have to sing for her supper. I don’t know, we’ll see if she’s available. She’s busy. She’s pretty famous; I don’t know if you’ve heard of her. She’s pretty backed up. Hopefully the guy who’s in charge will like her for that part because I’m going to suggest her.” - Jason Bateman

Here is the MTV video:

A statement like that needs to be followed up on. Good thing for us, Aniston was at the very same junket. Of course she was- they star in the movie together! Her response when the subject of “Arrested” came up was immediate and emphatic. - Adam Rosenberg

“I love it. I actually think I might have asked [Bateman] … if that was possible,” she said. “Anything to work with Jason.” - Jennifer Aniston

Sounds like a lot of If’s at this point but it’s exciting news.
