I'm still sort of shocked that Larian doesn't just flat out say without any ambiguity at all "There is no longer any 72-hour early access for Early Access players on PC" or "Yes, July 31st will be the release date for those that purchased Early Access" and put it in writing on their social media/forum/main page/whatever. This isn't a small indy company were dealing with here. For Sven to say it so casually during a PfH but no official indication is just strange.
They might be hoping to do the EA but are unsure if they can and so are waiting until they know for sure.
