It was revealed today that the upcoming return of Arrested Development has landed cameos from comedic heavyweights Kristen Wiig and Seth Rogen.

Season 4 is set to focus on just one member of the Bluth family at a time per episode, so its likely that these guest star appearances will be a one-off deal. Seth Rogen's role on the long-absent series was not revealed. Though, the mystery behind Kristen Wiig's appearance has been lifted, and it's safe to say that this intriguing bit of insider information is a Major Spoiler for fans of the show hoping to be surprised when Arrested Development becomes available on Netflix this spring. Turn back know if you don't want to know...

Wait for it.

No. Kristen Wiig will not be playing Tracy Bluth, long deceased wife of Michael Bluth (Jason Bateman) in a flashback. Though, she will be appearing in a flashback. The actress is portraying a younger version of Lucille Bluth (Jessica Walter). No further details were given, but that certainly is a cameo full of promise. And if they are flashing back to a young Lucille, it is possible that we will meet Tracy after all. Who do you think should play the mysterious role of Michael's never-before-seen wife? Or should we never see her?

Other confirmed guest stars appearing in Arrested Development this year include John Slattery, Conan O'Brien, Andy Richter, Isla Fisher, Terry Crews and the Workaholics, Adam DeVine, Blake Anderson and Anders Holm.
