I actually think it would be wise for the estate to release a lot of rehearsal footage. - as bonus on concert DVD's and Blu-Rays.
here is why:
Some people say he did not have the energy to perform TII - and their argument is the TII film. MJ does not dance like he did on concerts - he did not even make the moonwalk in BJ - some even claim he could not moonwalk any longer... Stupid.
BUT - if they could see fx Dangerous rehearsals BJ - they would see that in that rehearsal he did NOT make the moonwalk neither!! - And the dancing was very slow compared to the actual show.
We fans know of course that many times he just marked his moves, walked around and watched the dancers, came with instructions (There should be a stair here so I can grap some girls - the piano is too loud etc. etc.)
But those who have just sen Dangerous and BAD concerts and then see TII do not get that MJ of course did not perform a hundred per cent at rehearsals. (or sing a 100%) - why would he?
But to all those who claim MJ had lost it in TII - give them Dangerous and HIStrory concerts with rehearsals as extras so they can see the difference. - That would stop all the nonsens.
