The multpile marriages, the divorces, the trend chasing and the herpes crisis ruined any possibility of Usher having any type of comeback. Have people not paid attention to his latest "album" flopping? The drop in social media followers across all platforms? A confessions like album in 2018, wouldn't be as effective as it was in 2004. It's not as easy to shock people now, we've seen it all. Artist do have expiration dates as far as their commercial appeal. After that's gone, it's up to them to maintain their base. I still love 8701,Confessions, and Here I Stand. Usher has nothing left to prove but a comeback isn't going to happen, at least not anytime soon.
