Steve Lee podcast had Robert Carranza on who happened to mention that he "just finished up [Marilyn Manson's] new record." https://youtu.be/ZSvrH_pZC_M#t=16m32s
Steve Lee had him on was because Robert Carranza mastered his band's (Mangchi) last album. So by "just finished up" I'm assuming he means mastered. Which means the album is finished. I don't know if this is new information of if we already assumed the album was finished.
