Showrunners Craig Mazin and Neil Druckmann played coy but confirmed that “more than one is factually correct.”
No way," Mazin replied.
“It’s more than one season,” Druckmann added.

Pressing further didn’t shake their resolve.
They wouldn’t give up more details.
“You have noted correctly that we will not say how many.

But more than one is factually correct,” Mazin said.
“But it’s going to be different and it will be its own thing.
It won’t be exactly like the game.
It will be the show that Neil and I want to make.But we are making it with Bella.”
He also noted that season 2 is also shaping up to be “more massive” than season 1.
In other words, buckle up!
