So 1D's preorders are up to 200K, which is double ARTPOP's. Assuming they double Gaga's first week sales, the same way they double her preorder, that would mean a 520K opening week.
If they drop, say, 60% second week that's about 208K. We'll see if BJ can scan as much. Pre-orders are doing better than FF right now thanks to the snippets spreading around.
How do you know it?
But anyway, if Britney can't scan past 150k in ****ing December, then she is REALLY done.
