That is not neccesarily true. One big reason they have so many gears is because they eliminate any sort of chain reduction entirely and drive the center wheels from the output shaft of the last gear stage. I think that a meshing system could have the potential to have less gears if done in a slightly different manner than they do it. Either way, they obviously have an elegant solution and it seems to be working great for them.
I will still put my vote in for the dog style transmissions. Of course
Also, Dave, drop me a line sometime. We are creating a service learning class next quarter with the ME department so we can get credit for helping out the high school FIRST teams. You might be interested.
