The album was at 735k last time we got sales for it in January. By now, it's passed 750k.
However, the problem is the album left on a low-note. Its last single was one of Britney's biggest flops, she came off her most unfavorably received era and the general public just wasn't feeling the material.
She will have to really come back HARD next time around for Femme Fatale to even get a small rise in sales because right now, she is not in the limelight and it's not looking good. The album may pass 800k in Nov/Dec, but it'll have an uphill battle from there.
FF wasn't unfavorably received when it's has a high Metacritic score and her singles did amazing. It's her album sales that are continuing to drop.
when the album first came out she should have done alot of promo for it cause it has alot of nice pop/dance music. she should have came back with inside out to finish the album. but yes i do think it can sell 1,000,000 !
If Britney really cared about album sales, she would have achieved this feat a long time ago. But she knows where the true tea is at. It's a singles world and she is one of the reigning queens of selling singles. But on topic, FF most certainly will sell 1 million in about 2-3 years or less.
