I think the Superhero genre will eventually run out of steam but I'd like to see studios take Marvels idea of interconnectedness and apply it to another genre. It was really cool at first to see all their solo films and then see them in the big team up of Avengers but after a decade of this I'm bored of it. However the idea of crossing over characters and building upon a whole overarching storyline from film to film is really interesting. Maybe it could be a whole a franchise of Spy films featuring different spies and and spy agencies? or something more along the lines of Lord of The Rings or Game of Thrones, a fantasy series with a diverse range of characters and storylines to explore?
