When watching the YT video of the press conference there was this link to the answer for one of the christmas question contest (
Does the Witcher 2 Preorder mean that GOG will start offering more new games?). The answer was along the lines that bringing TW2 to GOG is an opportunity that cannot be missed, that they would be open for other AAA titles if the publishers could accept the 'GOG philosophy', but that it also could be that TW2 will be the only AAA title ever being released DRM free, and that they are told very often that TW2 will probably be pirated like hell.  
 The release date of TW2 is coming nearer and this will be a big test for the DRM free model on the AAA scale. The interest in TW2 will probably be higher than even Baldurs Gate or any other title on GOG so far and the price is much higher - it's not a bargain like GOG's titles. More incentives for piracy.  
 I am convinced that the DRM free property of TW2 will not make much difference in offering a non-copyrighted version of TW2 on a torrent -breaking the SecuRom will not be impossible. However piracy cannot be made any more easier than downloading here and starting to distribute. But in the end, the difference is maybe only a couple of hours.  
 However the question is: will TW2 be pirated like hell?  
 Even if it is not the fault of the DRM free approach, a high piracy occurence will surely be used as an argument against DRM free. I don't comply with it, I just say what I think will happen.  
 If you say that piracy cannot be stopped effectively now, than anyway only the paying customers matter. TW2 is so rich with additional content - this seems like the best they can do against piracy. It would be so interesting to get to know how sales are distributed relatively on the DRM free and DRM full channel.
