How far future are we talking here?

In the very, very distant future, I'm guessing we'll see browsers with VR functionality accessed through a headset or something. Maybe with websites actually resembling 3D worlds akin to the 'cyberspace' fiction of yore.

Something involving AR functionality seems plausible too. Not sure how it'd work, but maybe the sites you're seeing would be like dioramas projected into the real world, akin to Pokemon GO.

But that's probably a while off. Coding VR/AR setups as web apps is still pretty complicated as of right now, and the possibilities for a browser that really depends on them haven't been explored all that much yet.

For the short term... It'll probably be pretty boring by comparison. Typical features from mobile apps and desktop programs will keep making their way into web development (I'm guessing screen snapshots, ambient light mode, more stuff involving the camera and gyro sensors in devices, etc) and eventually the web will start seeing them integrated into the mainstream more and more.
