Alright, fine, I'll predict. If anyone asks me for logic, I will scream. Four times is enough. Fine, I'll give a sentence.
First week: 600-700k. A little below. It has less hype, I suppose, and it's not an FPS, it's in a far less popular genre. But it also has the holiday on its side. This also means inferior legs to Uncharted in the first 10 weeks.
End of 2009: 1.3-1.7 million. I don't think it will get to 2 million, but it might come reasonably close.
