“The Big Bang Theory” Season 10 has yet to premiere, but there are already some rumors that the upcoming installment could be the last for the hit CBS TV show.

During the recent Television Critics Association summer press tour, CBS chief Glenn Geller told reporters (via Entertainment Weekly) that he's confident “The Big Bang Theory” will be renewed for Season 11. The exec also shared that while some of the cast members’ contracts will end after Season 10, he knows everyone would want to be part of the show for more seasons.

“We are very confident that everyone involved wants more ‘Big Bang’ past year 10… I know Warner Bros will make those deals,” he said. Geller added that if it were up to him alone, he would not take “The Big Bang Theory” off air as long as there are fans who still want to watch the show.

Meanwhile, “The Big Bang Theory” showrunner Steve Molaro talked about the fate of the CBS show following the Season 9 finale episode. While speaking with the publication, Molaro said that he already has some ideas about how he wants the show to end if Season 10 will indeed be the last. “I have personal thoughts that have been floating around in my head, but we haven’t really talked about it. It always seems like this thing that’s off in the distance forever. Until it becomes closer to reality, I’m not going to think about it all that much, because it makes me sad,” he said.

In other news, CBS confirmed the casting of “Breaking Bad” alum Dean Norris for a multi-episode arc. Norris will play the role of Captain Williams, a tough Air Force representative who will be interested in Howard (Simon Helberg) and Leonard’s (Johnny Galecki) invention.

“The Big Bang Theory” Season 10 will premiere on CBS on Sept. 21 at 8 p.m. ET.
