In einem neuen Interview hat Kevin Cloud von id Software folgendes von sich gegeben:
Kevin: The group of people at Gray Matter is huge fans of the original game and had wanted to do a follow up for quite some time. They did a ton of research on real Nazi projects and experiments during World War II, took it a slight step further (although youd be surprised with the bizarre stuff the Nazis believed and were trying to do). Weve used the X-Files type analogy a number of times, but they really did do a great job mixing the bizarre ideas and imagery with the more familiar World War II settings, to create that type of feeling when youre playing. There will be another Wolfenstein game. Hopefully we´ll get a chance to work with Gray Matter again. Drew and I will probably meet sometimes later this year to discuss it.
