I saw it! It's Alive! It's Huge!

After the trailers played before Transformers, there was another preview, which no one knew anything about. Even reviewers and those in the know were taken by suprise. It ran without introduction, and without a title. Only a release date.

Discussion has been raging... is it Godzilla? Voltron? A tie in with the producers TV series, Lost? 1-18-08... is that the release date, or the title hidden in plain sight? Just about the only thing that is known is that it is a giant monster movie, told from the point of view of a few average people.
