"No, he’s not in our game," he said with a smile. "We’ve got to save something for future Wolfensteins. We can’t do him in yet!"
"That’s one of the cool things again about the Wolfenstein universe: we go back and we pull some of these things from real history and spin this what-if story for some of it, and some of it just kind of blows out," he said.
"So like the Kreisau Circle originally is more of a group of aristocrats working behind the scenes in hopes to overthrow Hitler. Here, they’re gun-toting resistance forces fighting on the streets. But it’s kind of nice to take those elements, have a framework of reality, and build it out."
In other words, fans will have to get back to the original Wolfenstein classic if they wish an encounter with a robotic version of Hitler. In the next game, hero BJ Blazkowicz will have to prevent the Nazis from further using n ultimate energy source, called the Black Sun.
Using such a power causes the appearance of the Veil, a rift between dimensions, as well as granting out hero several special powers.
