The problem with doing an updated TRA is that there's no new audience for it. He's already sold all the copies he's ever gonna sell and hasn't created an entirely new fan base that's going to invest in a new copy.
Normally you update or revise books like that when they're extremely outdated or when it's no longer in the limelight and you have a whole new customer base for it. Neither applies, so who's gonna shell out another $40 to hear him talk about stuff that's really old news by now? Remini's show has been off the air forever and her star is falling fast so no reason to brag about that, and he hasn't done anything significant since then except confess to dallying with prostitutes.
He's also already tried to spin that story in his favor and that hasn't worked. Any mention of it in a new book to a new audience risks having them react the same way; not buying his BS "we're all imperfect and it's all apostate lies anyway" and instead, losing them as viewers.
I doubt he'd sell any more than maybe 100 copies of TRA v2 and it would do more damage than good. Plus he doesn't look like he has the clarity or sobriety needed to do it anyway. Something is seriously wrong with his health, judging by his IG videos alone. I don't see good things for him in 2024, NGL.
