If Michael's legacy is as good as we all think it is, then rushed re-releases, compilations and posthumous albums are worthless. They may sell a few records at the time, but his legacy is bigger than a 2 disc re-release of Dangerous.
The Beatles got nothing until the anthologies in 1995. They didn't need anything, and their legacy had already been cemented. It's almost like this need for re-releases and such is based on a fear that Michael will be forgotten. How in the name of christ can he be? Sure re-releases get a few more sales over the line, a few more listeners. It's second fiddle for me to the work that Michael put in during his lifetime that has immortalised him in time, and will always be referenced in history, most important artists lists etc.
Sure, new things are nice, but we don't actually need a physical re-release of Dangerous.The album is as good as it will ever be. That is the fact. Hopefully the online campaign will step up and a few more people will buy whatever version is most readily available online, Mp3, Special Edition CD or Vinyl.
I think Michael is fine. He will outlast the lot of us. He will always be referenced, talked about and remembered in the respectful artistic way he should. His work will stand the test of time.He'll be fine.
