It's now unclear. It might be The Witcher for consoles.
British Eurogamer were told it was Witcher for consoles.
http://www.eurogamer.net/articles/2011-05-24-new-witcher-game-to-be-announced-at-e3 Czech Eurogamer were told it was something completely different.
http://www.eurogamer.cz/articles/tvurci-zaklinace-predstavi-novy-projekt Update - British colleagues from EG with Polish producer of our initiative talked on the phone and told them, surprisingly, something completely different than us in an e-mail, although it is unfortunately not yet possible in public. Anyway, when the authors had previously said they do not handle multiple projects at once, did not lie:) And for all the following quotes speak for producer Eurogamer.net : "Console game players that might be interested."
However, they are only handling one project. So this Witcher for consoles/not Witcher, but also for consoles is the same game.
