Elder Scrolls V: Skyrim wasn't enough to get your dragon-murdering blood going, maybe this little bit of info from producer Todd Howard will: "There is an unlimited number of dragons" in the forthcoming game, he told Norwegian magazine Gamer.no (according to a fan translation on Bethesda's forums). Not only will dragons appear in scripted encounters, but they'll also be randomly generated in the gameworld.
The translation also notes that "all dragons speak" in the game, with Howard fu rther explaining "it's actually what they do when they are spouting fire." He hinted that some dragons will be able to communicate with the player in "the common tongue," though we're distinctly worried about what happens when a dragon can't remember the "common" word for something. Does he try to pronounce it in dragon, and accidentally set ablaze whoever he's speaking with? Either way, it sounds dangerous.
