Yeah, but the other possibility is that our tech hasn't lived up to our expectations, and therefore we haven't made the observations and measurements we might have hoped for, which I'd wager is far more likely. "Hot Jupiter" type planets aren't as much of a revelation as one might expect, however, given the prevalence of binary systems, many of which have very, very short periods (J0106-1000 has one of 39 minutes) - and there's still nothing to say that those same systems don't have rocky worlds tucked away that we can't see due to the overwhelming noise from the massive inliers.
