I think it can do around 130k first week in NA, with a LTD of around 600-700k.
It already has over 70k preorders and will probably end up with around 80k, first week sales should be roughly double that. So I think even as high as 150-160k first week is a possibility.
1 million combined for the West when it's all said and done, giving the game a respectable 2+ million sales total.
