In recent exoplanet meeting "The Next 40 Years of Exoplanets", there was much discussion of the inablity of the community to agree on whether to support coronagraph missions or interferometer missions, with white papers for the decadal survey contradicting each other, saying only their preferred method would work and the other method wouldn't work, with the result that both SIM and TPF have been cancelled. Geoff Marcy said he was unhappy about the last ten years and unhappy about the next ten years and said the title of the Astro2010: The Astronomy and Astrophysics Decadal Survey which is "New Worlds, New Horizons in Astronomy and Astrophysics" is disingenuous in the use of "New Worlds" because SIM and TPF were cancelled.
Has the community since then reached a consensus as to which method is preferable and what are the deciding factors ?
