The Witcher 2 - Preview @ Games Radar

Games Radar have a preview up for CD Projects upcoming game The Witcher 2.
They have talked with Tomek Gop, Witcher's 2 senior producer. According to the preview TW2 will intensify everything seen in the first Witcher game. Here's the bit about how the story will unfold in TW2:

“I think that the story that we’ve written for The Witcher 2 is definitely bigger scale,” Gop says. “Whenever you make a choice, or do anything, you will see that it influences a lot more than one or two people. It might change history. We really pride ourselves on the moral ambiguity and choices you make. We don’t put them in the game because we have to have ten choices per chapter, we just think that they naturally fit in the story that we’ve created. And the difference in The Witcher 2 is that the world is going to change a lot more in the second part depending on your choices. Places will look really, really different due to your actions in previous chapters.”
