Not sure if any of these have been answered already, but:
1. Are Acts level capped?
I'm not even sure how I'd feel about this. There are good arguments both in favor and against using this expedient.
2. What is the final origin companion count?
I'd be more curious to know the number of companions in general, regardless of these being "playable Origins".
And yes, I'm saying this because I'm under the impression these numbers will in fact be different.
Metacommentary aside, thinking on my feet I can't come up with a single question that I would expect them to answer openly.
Maybe: "So, are we getting this partial or total revamp of the dialogue system that will allow more party members/companions to contribute to a conversation?"
