If it really took 8 years to arrive to this point, I think the answer is simple : Trey didn't give a shit for like 7 years and now he needs money to buy this lamborgini (which he took a picture with), so he takes 2-3 months to write this half-assed album with much commercial appeal for hot topic kids and releases it. He probably doesn't perceive MA as his ART anymore but only a way to get his paycheck.
You have elucidated a point I have held inside myself, and hope it is not the case.
(though in reference to that pic itself, I believe it was the owner of Dean guitars, but point well made nonetheless)
