Supersized rocky planets are out there.

Yes, I'm aware of that. I'm also aware that there are a number of other detection methods which aren't - which is why I asked the question.

ETA: It's an entirely separate matter as to whether or not earth-size/mass planets are *as easy* to identify as larger/more massive ones. In other words, are we finding fewer of them because they are fundamentally harder to detect - which they are.

If Kepler found fewer than expected there are two possible reasons:
A) Kepler's design was flawed.
B) Our models of the dynamics of solar system formation are wrong.

Where's C) gawd dun did it ?
