It reminds me of the upcoming Guild Wars 2 game (release date unannounced) that has five dragons rising up to cause major geographic and political changes in the world of Tyria. But I guess dragons are a common enough trope in fantasy that it's unsurprising "Skyrim" will feature them. I also wonder how this will compare to those in "Dragon Age".
Hopefully they won't be the same as in Dragon Age.
"Bullet-sponge" enemies for the sake of "omg there is a boss critter with LOOT" isn't what I want Elder Scroll dragons to be. Even with the bullet-sponge properties dragons, drakes, and dragonlings got to be routine. Made some nice armor once you got to Wade, but still.
Now, dragons as sentient, intelligent beings, possibly with their own agenda? Much better.
