Legendary/Warner Bros has announced the official website here not to much on it yet but more will come I'm sure.
The end of Legendary's panel gave monster fans a bit of a surprise Skull Island and King Kong look to return to the big screen, below is from the panel via Newsarama.
One more piece of footage was shown to close out the panel. It's a Skull Island teaser trailer, with King Kong featured last in the shot. This was the secret movie with Universal Pictures based on an established property Legendary teased several weeks back (the one some rumors pegged as a Namor movie).
"Prepare to explore the mysterious and dangerous Skull Island. In theaters November 4, 2016," Legendary tweeted after the panel, later adding in a press release: “Previous works have touched on the island, but staying and exploring this mysterious and dangerous place offers Legendary the opportunity to take audiences deeper inside this rich world with a style and scope that parallels other Legendary productions.”
