Slightly Off-Topic, but I've just read this very old article (February 2002) in German about Guido Henkel:
http://www.pcgames.de/?menu=060301&article_id=32590&page=1He was an important person behind the Realms of Arkania (The Dark Eye - conversion) - Trilogy as well as Planescape: Torment, one of the best RPGs ever, in my opinion.
What I didn't know is that he was offered to produce Wiz8, but he refused the offer, because Sir-Tech was situated at the canadian border. He shun away from the cold winters he expected there.
That's a pity, it would have been interesting to see, what Guido had transformed the Wizardry-Series into!?!
Best regards
