Yes, there will be. J.K. Rowling has been quite engaged with this series and given its popularity, it's very likely she'll continue writing more Cormoran Strike novels.
I don't think so. J.K. Rowling seems to be taking her time between novels in this series. And since there are no hints or news about a new one, we may have to wait a while.
As of now, there is no definite information regarding a new Cormoran Strike novel. The previous novels in the series have been well - received, which might suggest that there could be more in the future. But we have to consider that the author, J.K. Rowling, is involved in multiple projects. She might be exploring new ideas or working on other stories. The publishing world also plays a role. If the publishers see a high demand for a new Cormoran Strike novel and if J.K. Rowling has the time and inspiration, then it's very likely that we will see a new one. But until then, we can only wait and hope.
J.K. Rowling, who is famous for the Harry Potter series, decided to use a different pen name for these detective novels. By using the name Robert Galbraith, she was able to explore a different genre without the huge shadow of the Harry Potter franchise. The Cormoran Strike novels have their own unique style and tone that is distinct from her previous work.
