The devs have talked about this multiple times. That they expected 5E to be the last edition ever published, it was basically time to close up shop. There's a thread on it here https://www.enworld.org/threads/rob...-at-wotc-during-the-5e-dev-and-launch.699643/Where is your quote or reference that they intended to lay the game to rest? Am I misreading what you're saying? Because I've not read that claim from anyone actually behind the game.
