Unapologetic was at 3.48 million back in February.
In half a year that's where BEYONCÉ will be as well (unless she dies or something or wins AOTY). So for now we can say the albums have sold exactly the same.
Beyonce is at 4 million according to Mediatraffic.
Their last update said she's sold 2 million copies this year + the 1.4 million copies from last year.
I also tried to tell people that Gaga winning 8 VMAS in 2010 was basically MTVs way of saying they knew she would be irrelevant sooner than later so they may as well just award her now and get it over with.
I don't PRISM ever passing BEYONCE if Bey is still selling half of what Katy is while having such a huge gap between them. Not only that, but the awards season will give Beyonce many random boosts, not to mention her HBO concert series (in full) airing on HBO in September.
