Do we know how much of that completion time for finishing is including doing some cauldrons? If those are as big as most are saying those hopefully add a decent bit of time to the game.We have no idea unfortunately. So in reality we don't really know how long it will take to 100%. Its pretty much guaranteed to be 40+ hours no matter your play style but there isn't any upper limit yet. That being said, I'd be surprised if it will take more than about 80 hours to complete fully.
