I'm very much looking forward to it. In fact I don't think I've had this much anticipation towards a game release in years.
Replaying the first game now, despite the games occasional flaws I'm just struck by the sheer breadth and scale of the game and how damned close they came to pulling it off despite using an archaic game engine and it also being their first attempt at a game. I mean The Witcher was made using the Aurora engine, best known for the original Neverwinter Nights, and yet it still managed to look breathtaking in places and even now looks quite nice thanks to the level of detail the developers have put into every little thing. Having read what few books of The Witcher series have been translated to english, I can also appreciate the level of detail they put into the setting and story as well. This is obviously a company that cares about the setting and story and wanted to stay as true to that as possible with fantastic results.
So the thought of this same team now with some experience under their belts, a better engine to work with, and a higher budget is a beautiful one. And everything I've seen and read about the game indicates that this could be something special.
I mean that article you link to was written by Alec Meer, who actually disliked the first game. So if after playing the preview code of the game he's that excited you can't go blaming nostalgia and whatnot, the games standing alone. Can't wait to see why!
