10 Cloverfield Lane, is there actually going to be a sequel?

The Twitterverse has been buzzing since the release of the mysterious 10 Cloverfield lane trailer. Yet the question on everyone’s lips is, whether it is actually a sequel.
J.J Abrams, a producer of the original Cloverfield labeled 10 Cloverfield lane “A blood relative” but what is the film about? Starring Mary Elizabeth Winstead, John Goodman and John Gallagher,  Jr. The trailer reveals certain elements that echoed the first but at the same time gives away little. From what I can uncover the majority of the film involves the three characters listed above stuck together in an underground cellar and a lot of stuff happens. There’s a fire, there’s an earthquake, Goodman gets a wineglass to the face and they should NOT go outside. Of course Winstead yearns for freedom but whether she opens the door or not, we’ll have to wait till March.
