Alicja Bachleda-Curuś voices Anya Oliwa in Machine Games' re-boot of id Software's classic. Having achieved reasonable success with Wolfenstein: The New Order since launch news of a sequel was only a matter of time.
Now it seems to have been confirmed thanks to Alicja Bachleda-Curuś, who accidentally (?) answered the question if she still works with Bethesda like this:
"I'm working on a video game, first part of which I have already made. Now we're making a second one, which will take two more years. I played this game as a child. I was very happy when I got to the point where I could shoot Hitler."
That means we shouldn't expect the sequel to Wolfenstein: The New Order anytime sooner than 2017, and it should also be noted that since the project isn't officially announced yet lots could happen before we actually see it released.
Thanks, Game Pressure.
