I’d be extremely pleased to be wrong, but after the last update I’m not expecting any more race, class or companion reveals other than the final promised origin.
I’m wondering if we’ll find out more about a third antagonist, as we were told we would get info on three in the run up to the game. It’s not something I desperately want, but did find the Ketheric and Gortash reveals interesting so perhaps I’d be glad in hindsight.
As others have also said, though, my main hope is to get to see the final(ish?) version of the gameplay in action. And specifically to get a glimpse of whether my top hopes for changes have been implemented so I can either relax and stop worrying about them or have some time to get over my disappointment before my first playthrough

I’d also be really interested to hear more from Larian about the process of developing the game, and specifically how Early Access has changed how it has shaped up. But tbh I can wait until after release for that, and really just want as much (non-spoilery) info about the game as it is now as possible!
