I hope at some point in the future we get the Victory Tour concert Michael had filmed for release on home video until the rest of the jacksons blocked him from him releasing it, really like to see that.
One of the reasons Sony didnt want to provide the prosecution with unseen footage from TII was because it would interfere with anniversary release, hope we'll get to see more footage of him rehearsing Dirty Diana, Dangerous,Will You Be There, We Are the World, Heal the World, Stranger in Moscow and Don't Stop 'til You Get Enough.
As for the Queen songs I havent heard anything more than this

"Michael [Jackson] used to come and see us when we were on tour in the States. He and Freddie became close friends, close enough to record a couple of tracks together at Michael's house, tracks which have never seen the light of day."
Asked when they will come out, May replied: "(They'll be ready) in the next year. We've been talking to Jackson's estate and they're happy."
Queen have previously announced plans to release a new album of old demos featuring Mercury, with May revealing that he had been going through the band's old material with drummer Roger Taylor to compile a selection of unreleased tracks for a forthcoming LP. It is unknown whether the Jackson duets will be released as part of this or not.
