I see annafan caught this already but I wanted to second her catch. The techniques used for finding planets outside the solar system, light and wobble of stars, are at this point in time only suited for very large planets which are gas giants.
It does seem they have discovered a rocky planet. My guess is it would still have to be pretty large. If its not then perhaps the observations/calculations are finally getting good enough to hit smaller planets.
The best estimates of if we are "special" will come when we know for sure we can detect small rocky planets at very great distances, but discoveries of such planets do not start multiplying quickly after we have that ability.
Right now it is definitely too early to tell.
