Erm, read the article again. It is being proposed that the model might be incorrect because we haven't found any stable terrestrial planetary systems yet. My point was that we haven't found any stable terrestrial planetary systems because our detection methodology favors the location of elliptical gas giants. They are basing their suppositions about the formation of planetary systems on flawed and heavily biased data.

Nothing found to date invalidates the standard model for planetary formation, or even throws it into any kind of serious question.

The orbiting earth detector telescope is due for launch in just a few years. Earlier they had looked back at earth to get our characteristic signature in case they spot another earth out there so they would recognize it.
