Cosmology is entering one of its most exciting episodes in the next couple of years, seeing an unprecedented improvement in the quantity and quality of data. With this in mind, we present new results updating the current constraints on the energy density and equation of state of dark energy. We critically consider how much can be currently inferred about the dynamical equation of state and how this may affect our observing strategies for the future.
