I'm just speculating, which is in a sense wrong - But I have a feeling that at Jermaine will do all he can to keep Michael above ground until he has convinced who ever he has to convince to let Michael be buried in Neverland.
I think you might be onto something here actually. I feel as though Jermaine is trying to persuade the rest of the Jacksons for a burial at Neverland too. Personally I'm torn on the idea. On the one hand it seems like a fitting place where Michael could be remembered forever by the fans on the other it was a place that brought home some sad memories for him and has been abandoned since 2005.
