How To Train Your Dragon was somewhat of a revolution in the computer animation world. Not in anything particularly innovative it did, but in that it showed that Pixar-quality animated movies could come from places other than Pixar. Heck, I think it's probably better than most of Pixar's most recent. Even better, Dreamworks didn't rush into making a cash-grab sequel. Now, it looks like the time is right for it to come to fruition because we have the first teaser.
Well, that's definitely a teaser. It doesn't show anything about the story, but I bet it will look great in a theater in 3D. It also shows what will probably be a skill significant to the plot: gliding. Of course, it's all about the character development, but I think that we can assume the film will provide for that as well.
Look for How To Train Your Dragon 2 in 2014.
