That interesting, it was already known that Michael didn't want to make tour, solo or in group after Victory tour but want to work in movies, imo it was a very good plan, because he could have made different kind of movies with different soundtracks without to fear to be too exposed, I remember to have read lot of articles in this website during Thriller/victory, and there are lot of movies in preparation, in solo and curiously including his brothers too, I remember the title "They Landed" and a movie in preparation with them and Tatum O'Neil for The Shaw Brothers in Hong Kong.
I'm surprised after Thriller, despite the controversy around this director, he didn't have asked John Landis to write and direct a movie for him, Horror director of this generation are well known to work very well and very quickly with modest budget who look bigger.
I'm shocked he (they) didn't put Victory tour in paper view, it's his best tour and would have bring lot of moneys, I think Michael could have convinced his brothers to make lot less concerts but in exchange they put that in cable/paper views etc...
For his future, there are an intesting interview from Frank Dileo during the Victory tour for the french documentary "Les Enfants du Rocks", it's around 8min12:
So, despite that Michael was tired of Tours, has clearly others goals like Movies etc...Dileo was already aware that Michael, and without his brothers, will make a solo European tour later (he wanted to make that in 85), it seem that Michael has no control of his own career despite what he liked to say, that these solo tours of 2 years who have been mistake, the tours with his brothers were always shorts; the fact that he was far less productive, the excessive surgery, the fact he didn't have talked about vitiligo sooner, his solo begin to be in playback etc...fans didnt realize that his reputation during Bad was catastrophic.
