nope News of the game's existence cropped up in September 2009 with a leak of some early footage, which prompted CD Projekt to announce the project along with its intention to release the game on consoles.
In March, CD Projekt's PR representative clarified that the engine used for The Witcher 2 is "capable of console development," but that the team was "focusing on the PC version at this time." In May, CD Projekt tweeted that it "always wanted and still plans to develop The Witcher 2 on consoles - nothing has changed.
While the company has historically been cagey about the console versions, this is the first time they have been referred to as a "potential" release. Thankfully, the PC version of The Witcher 2 is still on track for a March 2011 release.
