Still, at Wondercon in late February, producer J.J. Abrams had this to say about it:
We're actually working on an idea right now. The key obviously at doing any kind of sequel, certainly this film included, is that it better not be a business decision. If you're going to do something, it should be because you're really inspired to do it. It doesn't really have to mean anything, doesn't mean it will work, but it means we did it because we cared, not because we thought we could get the bucks. We have an idea that we thought was pretty cool that we're playing with, which means there will be something that's connected to Cloverfield, but I hope it happens sooner than later because the idea is pretty sweet.
