I guess Phil changed his mind
I really don't think so. I think the "Genesis won't exist after 2021" report was always a simple misunderstanding.
I think he just meant to say that Genesis won't exist after this tour. (Which I do believe will be the case.)
But I never believed that the tour would have a mandatory end date of December 31, 2021.
Not after so much money has been invested and so many rehearsals.
