Regarding Summer Game Fest, I’m hoping for new info too, but would think any announcements there will be focused more on marketing and attracting new players to the game, so perhaps an XBox announcement and a new trailer for us to pick over and try to draw conclusions from.
I’m also very much hoping for more info on companions, mechanics, classes and races in the run-up to release, but would expect things like that to come from PfHs/community updates rather than content showcased at industry events.
