Okay, let me preface this by saying this is one of those, "I know a guy..." stories, so I don't blame anybody being skeptical of what I'm about to say, but I swear, I do know somebody who was involved with Jack Ryan at Amazon, and they are currently working on another Clancy project elsewhere. Long story short, Jack Ryan was dead before the fourth season was even announced as the final one. Hell, it was dead before they even started filming season three. It was a shitshow behind the scenes and John Krasinski is difficult to work with. They fast-tracked seasons three and four to shoot basically one after another because Krasinski wanted out of the show to focus on his directorial career. The odds of him popping up in any other Clancy-related media as Ryan are pretty low.

As for Amazon owning the Clancy "franchise," I don't think that's really correct considering Michael B. Jordan's Rainbow Six movie is in development with Paramount (who unceremoniously dumped Without Remorse to Amazon in the first place), and the Splinter Cell animated show is going to be on Netflix. The Terminal List was a much bigger hit for Amazon than Jack Ryan, and seems like it probably cost Amazon a good bit less overall, too. Between that and The Boys, I do wonder if Amazon is starting to look more adapting newer IP instead of chasing legacy franchises, since most of their endeavors on that front (Jack Ryan, Rings of Power) haven't really been the shows driving people to their service, despite massive marketing campaigns.
