To further elaborate on your "probably never," many people like myself live quite a distance from the usual locations of both cloud servers and game servers. If you're not in the east or west coast of the US, it's probably thousands of miles. You can have the fastest gigabit fiber connection and it won't matter. Response time will never be acceptable simply because of distance and the limits of the speed of light.

I imagine that many people think internet latency is better than really it is due to the sophisticated predictive technologies currently used in games.
