In recent years a plethora of future surveys has been suggested to constrain the nature of dark energy. In this paper we adapt a binning approach to the equation of state factor 'w' and discuss how future weak lensing, galaxy cluster counts, supernovae and baryon acoustic oscillation surveys constrain the equation of state at different redshifts. We analyse a few representative future surveys, namely Dark Energy Survey (DES), Panoramic Survey Telescope and Rapid Response System (Pan-STARRS1), Wide Field MultiObject Spectrograph (WFMOS), Pan-STARRS4, EUCLID, SuperNovae Acceleration Probe (SNAP) and Square Kilometer Array (SKA), and perform a principal component analysis for the 'w' bins. We also employ a prior from Planck cosmic microwave background measurements on the remaining cosmological parameters. We study at which redshifts a particular survey constrains the equation of state best and how many principal components are significantly determined. We then point out which surveys would be sufficiently complementary. We find that weak lensing surveys, like EUCLID, would constrain the equation of state best and would be able to constrain the order of three significant modes. Baryon acoustic oscillation surveys on the other hand provide a unique opportunity to probe the equation of state at relatively high redshifts.
