According to Lineweaver and Davis, inflation continues today and has never actually stopped entirely. We are moving away from much of the universe at speeds > c and gravity alone will never be strong enough to cause a future contraction.
Inflation generally refers to a period in the universe's history in which the scale factor was increasing exponentially. It's true that we are superluminally receding from much of the universe even now, but this is not what defines inflation. Because of dark energy, we may be approaching an era very similar to inflation in which the scale factor increases exponentially, but again, most people don't refer to it as "inflation".
