hmmmm, is no creature spared from the dire threat of the Lycanthrope-template-horde, obsessive DM's that feel they have a right to turn every little, innocent creature into a were-creature. How about Were-squirrels? Wouldn't that rock, little furry creatures that hang around in the trees, sneaking up on people and attacking with a snarling, whining sound. Better watch out for your nuts man.
Anyway, I think there should be some connection between the different were-creatures. Instead of making bundles and bundles, a few (say 8-10) different ones that have some sort of common history, giving the different were-creatures a united feeling instead of the rather haphazard, un-organised way they are presented in MM. Hey, thats all, im spent.
