A common mass scaling for satellite systems of gaseous planets Options

Canup and Ward have a new, interesting paper ("A common mass scaling for satellite systems of gaseous planets") in the June 15, 2006, issue of Nature. See the Editor's Summary for more details.

This is an interesting point, especially when comparing the relative sizes of the major satellites in the Jovian and Uranian systems: two good-sized ones closer in, two somewhat bigger ones further out. (Saturn's system, in a way, is a hybrid: it resembles Uranus' with a Galilean thrown in for good measure).

Is Neptune omited from this argument (even though Triton roughly follows the pattern)?
