It might be a long while before fans get a new single-player update for Naughty Dog's massively successful title "Uncharted 4: A Thief's End."

This information was confirmed in an interview by voice actor Troy Baker, the actor responsible for the voice and motion capture for Nathan Drake's brother Samuel "Sam" Drake in the final installment of "Uncharted."

Baker said that Naughty Dog could possibly look into including his character Sam and Victor "Sully" Sullivan in the next DLC.

"After playing the game, I find myself really torn because a part of me wants [to see] what Sam and Sully are going to do," Baker told Twinfinite.

Baker also added some interesting ideas to the next DLC, like a quick look back into Nathan and Sam's past.

"I was so impressed with what Chase Austin did as young Sam that there's a lot of me that wants to see [them] go back," he continued. "We jumped from them being in the orphanage to the prison - I want to know what happened during that whole space in between."

Baker also mentioned the possibility of Nate and Elena's daughter, Cassie Drake, to be included in the next DLC.

Baker said that Naughty Dog is still planning about what to do for the next single-player DLC, as the developer is still recuperating from shipping "Uncharted 4."

"They're still batting about ideas, I don't think they've even landed on one." Baker said. "When you work with someone like Naughty Dog, you just have to trust them and I'm sure they're going to make the right decision."

The PS4-exclusive title sold over 2.7 million copies on the first week it was launched, according to PlayStation Universe. Naughty Dog also confirmed that the game is the last title in the "Uncharted" franchise.
