The inflation field mystery

I've been reading a book called "The Universe In Your Hand"
and it's doing pretty awesome right now.
It's really triggering some of my brain cells and new ideas.
So these days, I've read about the inflation field that might have triggered the Big Bang.
It saids that, before the Big Bang, there was this field called the inflation field that fills the Universe. And this field creates an anti-gravity effect, at the same time creating new bubbles of multi-universes.
So when the inflation field gets excited, a new big bang creates, so does a new universe.
Then, 8 billion years after our universe experienced the big bang, the inflation field finally have enough energy to wake its vacuum up and therefor triggered the extreme and sudden expansion of our universe. This is also why our Universe's background radiation and temperature can be so weirdly the same, even though they were so far apart and have never been in communication with each other, the inflation expansion can make two places that seems far apart been once so close to each other.

Here's the question:

It took approximately 8 billion years for the inflation field to restore its energy and then release. Our Universe is currently 13.8 billion years old, so does that mean the next extreme universe expansion will be in the 16th billion year? Which is 2.8 billion years later?? If so what are the effects of the inflation????

The only theories I know of relating to inflation are related to Guth's original work (and a few tweaks beyond that.) Generally the inflation occurs at a phase change of the Universe at large. The release of what I'll call "expansion energy" comes from a similar type of phase change: that of a supercooled fluid changing to a frozen state. (Obviously the term "frozen" is only in terms of relative temperature!) A perhaps better way of describing it would be to say that the cosmological constant abruptly changes and lowers over the course of the expansion, which acts as a sort of energy soak, and reduces the expansion energy.

My knowledge of the field is somewhat out of date but I had thought that all versions of inflation evolve from Guth's original idea. Surely the central concepts haven't changed that much since the 80's?
