Albrecht told reporters at the TV Critics tour that the sci-fi drama's future is dependant on the schedule of series creator Russell T. Davies.
"Torchwood is not one of the shows we went into thinking about a yearly return," he explained. "It's about Russell T. Davies [because] he has a lot of things on his plate. If Torchwood is at the top of his list, that will effect the future of Torchwood."
Davies is currently developing a new drama series named Cucumber with Showtime, it was announced last month.
However, the showrunner previously told Digital Spy that he was having second thoughts about leaving Torchwood.
"I say [I'll quit] at the beginning of every year and then I get to the end [of the series] and I love it again," he explained. "So I don't know. It is time that I moved on and did something else, but we'll just see how well [Torchwood: Miracle Day] does."
Torchwood: Miracle Day continues on Fridays at 9/8c on Starz in the US and on Thursdays at 9pm on BBC One in the UK.
