Steinn Sigurðsson is an astrophysicist at Penn State. In his blog 2 1/2 years ago he wrote, "Corot (launched in 2006) could see tens of obvious short period transits in its field of view, giving us a less biased sample of the mass and radius of the short period transiting planets. Over the next year, it should also gives us tens, or hundreds, of longer period transiting planets, depending on how planets are distributed in orbital period and mass around nearby stars."

Well, years later COROT has announced just 7 stars with 10 planets between them. Does this paucity of announcements, and scientific papers, indicate that detectable planets are substantially less common than anticipated? What does this presage for Kepler results?
