That's why Kepler and SIM are so crucial -- Kepler to get an overall count of the numbers and sizes of planets in the habitable zones of a typical star sample, and SIM to get a more precise survey of ALL planets down to large terrestrial ones orbiting our nearby stars. (A gravity-microlensing survey would also be useful, to get a count of the frequency and size of planets modestly outside the habitable zone as well as inside it.) Only after these missions have been flown can we decide which version of Terrestrial Planet Finder to fund first -- since, if habitable planets are scarce, it would be better to fly the Interferometer version of TPF before the cheaper but less sensitive Coronagraph version.
