Just looking through MJ's US certifications for his albums. They need to be bumped badly.
Right now these are ready to update:
Off The Wall - 9X Plat (from 8X plat since August 2009)
Thriller -
3X Diamond (from 29X plat since August 2009)

Dangerous - 8X or 9X Plat (from 7X plat since May 2000

)
HIStory - 8X Plat (from 7X plat since 1999

)
Number Ones - 6X Plat (from 4X plat in 2009 - it has tracked sales of >5M in the US)
Michael Jackson's This Is It - 3X Plat (from 2X plat in 2009)
----
A little longer to wait, but surely close:
Bad - Diamond (from 9X plat in May 2013 [this number is
way behind but the lost sales can't be certified now])
Invincible - 3X Plat (from 2X plat in 2002)
XSCAPE - 1X Plat (from Gold in 2014)
----
Unknown
Blood On The Dancefloor: HIStory in the Mix - 2X Plat (from 1X Plat in 2000)
----
Likely nowhere near an update
HIStory Disc 1 - 2X Plat (from 1X Plat in 2013)
The Essential Michael Jackson - 4X Plat (from 3X Plat in 2013)
The Ultimate Collection - 2X Plat (from 1X Plat in 2013)
I imagine they'll do a big presentation for Thriller reaching 30X Plat/Triple Diamond and certify Bad as Diamond at the same time maybe.
