Remember how in Spider-Geddon they killed off Noir and then pretty much immediately brought him back after Into the Spider-Verse came out? Yeah, there's no way something similar doesn't happen to Ben imo. He'll be fixed. Marvel loves their corporate synergy, even if they often suck at it.
I get that, but they don't have to give him an ongoing I feel, he could just appear in more mini-series written by JMD. But it's not like Ben's solo title did horribly either, it lasted as long as Kaine's did despite (admittedly) being far worse, and it lasted longer than Superior Spider-Man Volume 2 and both of Spider-Gwen's last two ongoing titles. Maybe Spider-Verse will be what Ben needs to find more of an audience. Not holding my breath on that, but you never know, really.
EDIT: I also find it likely that when they do fix Ben, they'll end up making him closer to his incarnation in Across the Spider-Verse, again like what happened to Noir. I haven't read that last mini in a while but it did feel more similar to his character in Into the Spider-Verse.
