@Virellius well, I'm pretty sure someone from the Paizo team wrote during the announcement that we will have ONE updated module which apply the THREE books update but that we will need to pay for it on top of the new uptaded book.
Also you didn't answer, do you have the pdf for free when buying the hardcover? It's usually the case but I can't find it in my digital content. And I think it's super shady of Paizo if it's not the case. More than having to pay for the updated Foundry module.
