Definitely it will come, but not near future, it could be thousand of years and no one knows when the exact time. It will only starts once all resources have been gone all over the world and war could be triggered resulting of Financial crisis.
It is absolutely true that no one will know for sure. The nature of state-sponsored bubbles is that the elites will do everything in their (considerable) power to prop up the bubbles, until the effort is no longer worth the reward to them (ie perhaps until it would destroy the semi-free-market and semi-democratic nature of the system on which their power is ultimately based.) So there is no way for outsiders to tell exactly when the bubble will collapse. The average person simply doesn't know enough details about events.
That said, 'thousand years' is perhaps too long, based on the time sequence of crises in the past, in the top countries of the system, that I listed in the OP. Again, we have to take note of the *incentives* that are inherent in this system, where the elites are encouraged to destabilize their own system, as long as crisis doesn't happen under their individual watch.
