Apparently (didn't watch it myself), during the Friday 13th Dec) livestream they said they were planning to do preorders and collector's editions. But that was over a month ago and I'm not sure how that fits with the early access thing and whatever their current plans are. Maybe they'll still do them, they could offer upgrades for early access peeps to collector's editions for anyone willing to fork out a bit more cash.
Beyond that, I'm pretty sure we don't know yet. You'd think there would be though for such a significant RPG release.
