Video games as the next big storytelling medium. I say: duh! But this is also what's going on with graphic novels and comic books. For those of you in my generation, I can't emphasize how deeply video games -- especially JRPGs -- influenced my upbringing. They were my Tolkien and my fairy stories. They were my myths, my heroes, etc.
On that note though, I doubt that games will supplant the previous mediums entirely. http://sciencefracture.com/2014/09/28/video-games-the-next-generation-of-storytelling/
