Thank you for asking.
I don't have a comeback date for the mere reason that I would like to be surprised when it happens so I don't focus on that. However, if I was forced to guess, July 2011 has some strong arguments. He actually signed his autograph with the comment "See you July 2011". That was in May 2009.
The other guess would be that he'd appear at the first Cirque show. He actually started these negotiations before June 25th so what we are seeing come to fruition isn't just an effort on behalf of the Estate or Cirque. In fact, a lot of what we see coming to fruition now can be traced back before June 25, 2009. Michael is the genius behind his comeback, for sure.
Some others have felt maybe he'd return on the Oprah show but I'm not sure about that as many of Michael's supporters don't think very highly of her for not supporting him during his trial.
Before I became a beLIEver my focus was solely on helping to vindicate Michael by sending emails, comments, etc., to the numerous sites that have published false stories in an attempt to set the record straight and to hopefully sway some hearts to see the truth. That has remained my focus in addition to finding the truth about what happened on June, 25, 2009.
Blessings.
