its delayed (10 days wasn't it) so then it would come out the 31th of January
ontopic: I think it will sell about 650.000 firstweek becouse we already know the first shipment is smaller than galaxy (well actually now I think about it, they can refill them trough to whole week afcours, so it might be more).
In the us I think it might even sell over 2 million first week and in Europe over 1 million.
