Have you guys heard about this one ?

Gaia observatory

QUOTE
"The satellite will determine the position, colour and true motion of one thousand million stars and over 100,000 objects in our Solar System. Gaia will also identify as many as 10,000 planets around other stars. "
QUOTE
"Gaia will measure distance (from parallax) out to ~100,000 parsecs; for stars ~10,000 pc away, with a Vmag of ~<15, Gaia will measure their distances accurate to ~10-20%."

Good overview of current understanding of Gaia's stray light problem and its effects on observations.

Gaia enters routine phase:

"Last week Friday, 25 July 2014, Gaia started its routine phase by scanning the sky for 28 days using the so-called ecliptic-poles scanning law. This is useful to bootstrap the basic calibrations of the data. After these 28 days, the nominal scanning law will be used to determine how Gaia is scanning the sky. Although the commissioning phase has ended, some activities remain to be completed. The root causes of the stray light and the basic-angle variations have not been found yet."

New posted paper is claiming that Gaia will be able to detect 20,000 jupiter mass planets (15-27k technically) over its 5 year mission, and some 70,000 (!) over a 10 year extended mission. For reference, there are around 2000 known exoplanets as of today - and most of those are from the Kepler mission... amazing to think it'll increase by an order of magnitude over a decade. Gaia currently records information on 40 million stars a day - according to a recent tweet approaching 10 billion observed over the mission.
