Upcoming games in the future?

So I've played a lot of the mainstream games like Forza, Halo, CoD, RuneScape, Tera, etc. They are all great but nothing over the top. What I mean is that ever since Halo 1 was released and became a revolutionary game for the Xbox, nothing so revolutionary has come out yet that everyone plays/has played, except for Minecraft which was another milestone. RuneScape may be considered as well as Pokemon but they both lacked things like amazing graphics, immersive combat, etc. I know with the release of the VR machine Oculus Rift and the AR machine Hololens from Microsoft there will be many new games. But what should I expect? Are there some revolutionary games being developed right now that everyone is excited for? Or is there really nothing that great on the market? I want to know what the competition will be like in about 5 years (by 2020), is there any way to predict this?
So basically, what can I expect by around 2020? Complete VR? Something more?
