My issue is that fundamentally, it's no more possible now than it was at the beginning of early access. All we actually know is that patrons will for sure be acknowledge in-game, which frankly I'd think was assumed before now but not guaranteed. Larian's confirmation doesn't really mean anything in that regard. My theory was always that they'd be as undefined as the narrator, and Larian hasn't given any information that suggests this has changed. We're both baselessly speculating, you're just more optimistic about it.
I wouldn't say it's about being optimistic/pessimistic. I'm sure some players would prefer patrons left completely to their imaginations, whereas other players would prefer patrons to be highly detailed NPCs with lots of plot attached.
From my observations of the way Larian do things and other suggestive elements, I would be willing to bet a few soul coins on the later, but I have no skin in this race: I don't intend to play a warlock anyway.
