So I was lurking around on tumblr (as usual) and one of the How To Train Your Dragon blogs had posted something vague about Dreamworks aging up the cast for the second movie.
I was like "IS THIS REAL?"
So I checked out a couple sources... AND IT'S TRUE! OUR LITTLE VIKINGS WILL HAVE GROWN UP!!!!
They confirmed that the next movie is going to take place five years after the first. And to prove I'm not making this up:

We'll have aged almost as much as they have! (The first movie came out in 2010, and the second is due out in the summer of 2014)
And apparently the animation quality is going to be "Final Fantasy eye-candy" quality (not my words).
I am so excited. My friends and I decided that we are going to march into the theatre and sit in the front row on opening night. It WILL happen. :D
