From what he says on the video I would assume Larian has told him he'll be getting more material to show before release...
re: Ghent not the final build - the timeframe is very short from the preview to release so I wouldn't expect Larian to be doing many changes beyond bug fixing at this late stage.
Me neither but it's time enough to change stuff around and/or revert/add some things. There's a reason why we're not having those 3 early access days anymore and I doubt it's just because bug fixing.
