Of all the dragon footage seen we only ever see generic breath moves beyond physical attacks. Now while fire/ice breath are shouts and do allow Bethesda to say "Dragons use shouts too" are they going to use varieties of shouts?
Am I going to see dragons doing Whirlwind Sprint, Slow Time, etc or simply X breath from X dragon?
there are 20+ different shouts, each with 3 different levels.
I don't think we will see that many different types of dragons, but certainly there will be more than just Frost Dragon and Fire Dragon.
Also, the Jills (Alduin's lieutenants) will probably be able to make use of multiple shouts and I suspect that Alduin will be able to use every shout in the game (except the Summon Dragon Shout).
