Erk also calculated Jackson would have followed with four more world tours before he turned 65.
Palazuelos weighed in during a hearing on Thursday, noting that the Rolling Stones are still touring into their 70s.
The Jacksons will also try to convince jurors that he would have made a fortune off of a long series of Las Vegas shows, endorsements, a clothing line and movies.
Strong argued that Jackson had a history of failed projects and missed opportunities, calling Erk's projections "a hope, a dream, and not a basis for damages."
If AEG is found liable, the company's lawyers want the judge to tell the jury to reduce any damages by the amount Jackson's estate earned from the documentary made from video the company shot of his rehearsals. "If there is a benefit in it, then that is deducted from a loss," Strong said.
Jackson lawyer Brian Panish compared giving AEG credit for the "This Is It" profits to being "like you murdered someone, wrote a book about them and gave them the money."
Panish, who will deliver the Jacksons' opening statement Monday morning, said he was not sure who his first witness will be Tuesday morning. He did tell the court he will show several videos of the depositions given by AEG's top executives in the first week.
Panish and AEG's Putnam will each have two and a half hours to describe their cases to the jury in opening statements starting at 10 a.m. Monday.
The witness lists include many members of the Jackson family, including matriarch Katherine Jackson. Other celebrity witnesses on the list are Sharon Osbourne, Quincy Jones, Spike Lee, Ray Parker Jr., Lisa Marie Presley, Diana Ross and Lou Ferrigno.
