The problem with even releasing information about previous religions meaning much over the short to medium haul is that the cultural milieu for a millenium has been one god. So beyond that, I can foresee the development of some agnosticism/deism sorts of things, probably some atheism. But I see no possibility whatever of reconstituting Buddhism, Hinduism etc. even Judaism or Islam until some prophet comes along. And how often do we see Moseses, Jesuses, Muhammads, and Buddhas come along each millennium? So a Reformation might happen, but not a huge splintering beyond that over any short to medium term.
You ask how many times each millennium a prophet comes along? Let's see...
In the 16th Century there was John Calvin and Martin Luther.
In the 1820s there was a fellow names Joseph Smith.
In 1876 there was Mary Baker Eddy.
In 1894 there was Swami Vivekenanda.
In 1949 there was Gerald Gardner.
In 1955 there was L. Ron Hubbard.
In 1958 there was Maharishi Mahesh Yogi.
In the 1960s there was Abhay Charanaravinda Bhaktivedanta Swami Prabhupada.
In 1970 there was Sun Myung Moon.
In 1978 there was Jim Jones.
I could go on.
(Please note that I am not in any way equating the people named above; they are simply a handful of the hundreds of people in the last couple centuries who have founded new religious movements and gained some following).
Prophets are actually quite common. Prophets that get a significant following are not that uncommon. You are only thinking of the most prominent prophets in history. In the time of Jesus, there were dozens of other prophets. Especially in times of troubles, prophets will appear quickly.
I think it is quite plausible that there will be a surge of prophets to fill the vacuum as the CoGA collapses.
