They got engaged to close out 2010, but does that mean Clark and Lois will get married in 2011?

Producer Kelly Souders won't reveal that spoiler to TV Guide, but did tease at last week's Critics Association press tour: "There will be a big day for them."

Can fellow producer Brian Peterson reveal anything more? He says:

"They're going to have a big moment in their relationship. This last run is about not only his identity as Clark Kent and his growing identity as a hero, but also his identity as a potential husband. That is as much of who he is as a hero."

Peterson adds that Lois will "step out" as a journalist this winter in an attempt to escape the shadow of Superman.

What might that mean? Guess we'll need to tune in and find out. Smallville returns on January 28.
