'Big Bang Theory' season 10 spoilers, plot news: Leonard moves in with Penny; Who will Sheldon's new roommate be?
Top-rating CBS comedy series, "The Big Bang Theory" will soon air its landmark 10th season, and fans can definitely expect a lot of big changes in each of the characters' lives.

When the hit sitcom returns to the small screen this Fall, viewers will see the much-anticipated formal wedding of Penny and Leonard, along with Bernadette and Howard's journey to parenthood. Additionally, Raj will find himself in a difficult situation when two women are vying for his affection while Sheldon and Amy are off to another chapter in their relationship.
According to TV Line, there is a possibility that Sheldon will now be on his own once Leonard and Penny move in together after redoing their wedding vows. The new living arrangement will be a huge leap particularly for Sheldon because he has been largely dependent on Leonard since they began living under one roof.
There is speculation that Amy will be Sheldon's new roommate, but it remains to be seen if he will decide to move in with his girlfriend. Penny's mother is also expected to be introduced in her wedding since none of her relatives have made an appearance in the series since it began.
As the show moves towards its 10th year, fans can't help but wonder how long their favorite sitcom will be on air. In an interview last month on This Morning, Kunal Nayyar spoke about the possibility of the show nearing its end, even if the actors still want it to continue. "All of us on the show realise how lucky we are on the show and we treasure it," he said (via Metro). "We're not sure if there will be another show like this, we know it is special."
Catch the season 10 premiere of "The big Bang Theory" which airs on September 19, Monday at 8 p.m. EST on CBS.
