Will there be a progression wipe when the game releases?
Yes; so much of the game has changed over the course of early access, carried over saves could create more problems than the time saved playing. As such, we are wiping the game so all players start from a clean slate.
Beyond the gameplay-related side of things, there are a lot of adjustments, fixes, and additions to the story as well, so the wipe ensures none of the key moments and events are missed.
