As many as eight posthumous Michael Jackson albums could be released, thanks to the success of 'Xscape'.

Sources say there is lots of material in the vaults and Rolling Stone reports that "eight more albums culled from outtakes and repackaged material could be released".

"We got more surprises coming," says producer Rodney Jerkins, who worked as a producer on 'Xscape' alongside Timbaland and Stargate.
