Will 2012 be the year of Earth sized exoplanets? Trend says yes

The graph on the right (from Exoplanets.eu) is a simple correlation plot, graphing planet mass against year of discovery*. Apart from 1992 (when 3 planets were discovered around a pulsar), the lower bound on exoplanet mass seems to decrease every year.

If this trend continues, we might see a number of exciting discoveries in 2012; after all, the lower a planet's mass, the more it resembles Earth (in rough terms). Actually, the party has already started with the discovery of 3 sub-earth sized planets last week.

If 2011 was the year of super-earths, then will 2012 be the year of Earth sized exoplanets?

*Note that only sub-Jupiter-sized planets are shown.
