Straight from Billboard:

Unless something awfully crazy happens, next week Eminem’s “Recovery” will be the first album to notch three consecutive weeks at No. 1 on the Billboard 200 since March. That’s when Sade’s “Soldier of Love” wrapped a three-week run atop the list. Industry prognosticators expect “Recovery” to easily hold in the penthouse, as none of this week’s new releases will pose a threat to its chart supremacy.

The “awfully crazy” would be if Big Boi’s highly anticipated Sir Lucious Leftfoot was somehow able to move more than 150K units. Right now it’s projected to sell around 50K for the first week.
