One type of new media I'd love to see is: VR as a new media.
We've known that VR as a technology has slowly started coming into fruition, with headsets like the Oculus VR being developed. We've also seen the type of uses that VR has, and I can imagine VR becoming a big big part of our digital life.
I think there's a whole new level of interactivity to be had - imagine if VR users could join an artist while they're working, and it'll seem as though the VR user was right next to them, and able to observe the artist's process.
Have front row "seats" to a game you can't make it to, tag along on a cruise or vacation with family when you can't make it.
Alternatively, being able to dive into things like movie trailers or shows could become equally as amazing. There would be a whole new wave of learning how to connect older digital media, with newer VR techniques.
At some point, a virtual world that connects the world would be the absolute highest point for VR as a new media in my opinion.
I think VR could be the first step as a new media in creating an interactive experience that is much more than the types of "new media" that we know now.
