Before the 'Buy Z&W-campaign' of IGN I was predicting it would reach 500K worldwide lifetime. Now I say 750K. Not that the campaign will have a big impact, I doubt it. But IGN-reviewers seriously think it is a good game. That will generate good word of mouth and that increases sales over time. But word of mouth is not fast enough to come into effect until christmas, so the sales could be higher if the game was released earlier.
