In Vilenkin's bubbling universe, inflation was, by definition, eternal into the future.

In «The Quantum Multiverse,» Yasunori Nomura discusses the classic idea of a multiverse in which cosmic inflation led to an infinite number of «bubble universes» and an alternative theory in which such universes do not coexist in real space but rather are potential outcomes of observations, or «probability space.»
