I think that it's more likely to change fundamentally as opposed to any whiz-bang new graphics or ever-increasingly large worlds. While we *can* keep throwing in more polys, and probably will, visual fidelity, generally speaking, is more limited by artistic direction than technology these days. Especially on PCs, where things (generally) run at smooth framerates.
So, some kind of game-changer will come up, whether that's VR (with the all-important non-obtrusive headset... Trust me, 30 years from now, they'll laugh at oculus) or something else, it will be very different from now.
