There was an informal Q&A at the Seattle Open and after reaching out on Twitter I managed to get some info from it that I thought others would find it interesting.
There was some discussion about how GW functions on a company level, like the art department being entirely able to do their own thing without influence from the board, and that when they decide to make a thing it will have rules made after the design is finalized
Some questions were asked about upcoming changes or additions to current game systems, but they were very coy about answering those. They they did reinforce that they are listening and looking at the data a lot more than the company did in the past, so feedback is important
I got a great reply when I asked about the ancestor sigils on the Leagues of Votaan Kin, apparently there's going to be AI that are treated as Kin with equal standing as citizens, and that we'll see that on the tabletops as well
They mentioned that their app development team is pretty large (and growing) and that they are actively working on making the tech side of things a lot better, but they want to stay true to the legacy of the games and will strive to stoll have print media and analog tools as well
When asked about the recent codex balance, it was discussed that a lot of the codexes were balanced against each other before they were released (and subsequently adjusted) then the next would come out but still be based off the balance they had against the previous release
So it's a little bit of power creep, but they're doing their best to stay on top of it and it's not intentional. Sometimes a strategy is discovered that is really great but makes for a bad game experience, so they adjust for that sometimes too
There may be more but it was informal so people weren't exactly recording or taking notes so if I find anymore I'll add to this.
