Since we're visiting all of Tamriel this time around, we're going to be seeing the homelands of other races and no doubt those races will all have their own versions of were-creatures.
How cool would it be to see all different kinds of were-creatures from different factions?
The Dominion would have Werevultures and Werelions, the Pact would have Werewolves and Werecrocodiles, and the Covenant would have Wereboars and (insert here).
I think it kind of skips over the lore if they're not implemented, you can't just pretend they don't exist, and it never made sense when an Argonian could turn into a Werewolf, they have scales, scales =/= fur.
Also, if they decided to make each race have its own relative were-creature, it'd probably make the single-player ES devs think; "well, they did it, so let's do it too!".
What d'ya think, will we be seeing other were-creatures, or will we all be playing as a werewolf (I'm guessing the latter unfortunately, just to save on time/effort)?
