They are already there
Look, I'll say this straight:
We already have the officially censored German versions of games (System Shock 2, I Have No Mouth and I Must Scream, Shadow Man) alongside their uncensored English counterparts so if you see a game for sale and it has an English and German version, you have the choice of playing the English version without fear of ONLY getting the cut German version.
We know that the censored versions are already here for several games (alongside with the uncensored ones).
The question is if they will lock out members from certain countries (e.g. Germany, Australia) from the uncensored content. Right at the moment we can decide ourselves which version we want.
I'm interested in censored versions of the Witcher series, but haven't seen an option to buy it.
