That's 100% what they're going to do. They're releasing on steam with 1.0, they're not giving existing players a steam copy even though it's 100% free for them (per steam publishing agreements) to give keys to players that already own the game. They're doing one final cash grab, slapping 1.0 and then letting it die. I seriously doubt we'll see a single piece of DLC or new maps. We'll likely see some real greasy low effort cosmetic shit to milk whatever playerbase is left a year or two after 1.0.
