  We study the possibility that dark energy decays in the future and the
universe stops accelerating. The fact thatthe cosmological observations prefer
an equation of state of dark energy smaller than -1 can be a signal that dark
energy will decay in the future. This conclusion is based in interpreting a
w<-1 as a signal of dark energy interaction with another fluid. We determine
the interaction through the cosmological data and extrapolate it into the
future. The resulting energy density for dark energy becomes
rho=a^{-3(1+w)}e^{-\beta(a-1)}, i.e. it has an exponential suppression for a >>
a_o=1. In this scenario the universe ends up dominated by this other fluid,
which could be matter, and the universe stops accelerating at some time in the
near future.
