One more month and CBS' hit sitcom "The Big Bang Theory" finally returns for a 10th season. Here is a roundup of what's coming next season.

According to Entertainment Weekly, "Breaking Bad" star Dean Norris will appear on the series for a multi-episode arc. He will be playing Captain Williams of the Air Force department of Materiel Command. Even though he is a tough official in the said agency, he is willing to meet up with Sheldon (Jim Parsons) and the group for their quantum gyroscope for military applications.

Executive producer Steve Molaro previously hinted that the boys are a little concerned with the fact that the Air Force is spying on their project. The EP said, "They have no choice but to see what the Air Force wants and then go from there."

Many fans have been wondering whether the upcoming season 10 would be the last for the series or not. At the Television Critics Association summer press tour, CBS chief Glenn Geller expressed his confidence that the people on and off cam of the show are interested to be a part of "Big Bang" after season 10. Geller said, "We'll put it on for as long as everyone wants 'Big Bang' on the air. I hope it lasts forever."

Meanwhile, actor Simon Helberg told Fox News that he hopes to meet his character Howard's biological father next season. If Howard's dad cannot appear in person, he hopes to have his name or background to be detailed on the series.

Helberg is also excited for his character's wife Bernadette's (Melissa Rauch) pregnancy. However, the actor does not know when the things will unfold. "She's going to have a baby, but I have no idea when," he said.
