I really think the sales will be consistent for Beyoncé throughout the year and next year. I see her selling around this amount or more this week and it just leveling out for the next few months. I just see a lot of longevity.
Justin's album just came out today. Will she overtake him next week?
Most likely. I believe the "Journals" thing is an iTunes exclusive that's only available until Jan. 2nd. He's not really pushing it as if it's some major release and its probably just to promote his movie... and like someone said, Bey has physicals on her side.
