HitsDailyDouble projects that Eminem's album The Death Of Slim Shady will do between 270 and 290K SPS in its first week.
It will be Em's 11th number-one album and the biggest rap release of the year.
It will also knock Taylor Swift's The Tortured Poet Society out of first place after 12 weeks there.
However, it is a bit under the 300K industry sources were predicting for it.
