I don't know, it just looks like a €50 stand-alone expansion that could've been DLC for the first game. But now they get to sell it for more, and add new/more individual smaller DLC for this one.
Not been much of a fan of Frontier ever since Braben left. They started focusing very heavily on paid DLC since, especially back when for Elite Dangerous it was first just cosmetics, but they got greedy and now have paid early access for new ships, after the game was content starved for years. And before that instead of focusing on new content there was a long period where the only thing that got updated was a new microstransaction currency and raised prices of the DLC.
Doesn't feel much different with the Planet Coaster and Zoo games. They get littered with paid DLC, and it's almost taking The Sims forms of additional paid content.
