There was an Elite Founder's Edition, it included the base game plus any DLC they would release for GC3, but that starship has launched. There will be launch DLC, free for anybody that already owns or will buy the game within the first week of release.

FREE Launch DLC

We do plan to release the game with free launch weekend DLC which will go to everyone who has already bought the game and the people who buy it opening week. It's just ship design bling (nothing functional) but a special token of gratitude to you guys who have made this game possible.
