Does not matter, people who buy "consoles" don't care what is native or not. They just care if their game runs well.
And additionally, Witcher 2 is not really using a wrapper, at least not in the WINE sense of the word. Witcher 2 uses eON which basically does conversion of DirectX calls to OpenGL calls at compile time, not execution time. So it's arguably pretty close to native.
