Asmodee has created a GenCon site detailing information about Space Cowboy's upcoming games including Marvel Splendor. Along with an overview video of the game, a release date was set to Octobrr 23rd. You can visit Asmodee's GenCon website here: https://gencon.asmodee.com/

Edited: Advertising a Gen Con branded site is acceptable. The other one you tied to sneak in is not.
