Interesting article.

The scientists tought that Titan must have hundred impact craters but they found a few ones. Then the hypothesis of missing craters might be related to volcanoes, rain and settling soot - perhaps aided by an eggshell-thin crust.

One LPSC paper mentions a thick, soft, runny layer ("mud") on Titan's surface as a possible explanation, concealing craters in the same way that craters on Earth's ocean floor are concealed by the ocean's surface. Really, it seems to me that there are so many possible explanations for the lack of craters -- since we now know that Titan's surface is modified both by wind and "hydrological" processes, and by a high level of volcanic and tectonic activity -- that it will be a long time before we know what the main cause is. And Cassini by itself probably won't be able to answer this question.
