I would venture to hypothesize, based on the divide in the community and statement by 'Raze' recently that they are primarily focused on getting back to work on the game, that any comment on something as significant as this would have been made by now if there was good news for both sides.
Perhaps somebody brought up the fact that if Obsidian can do both systems with PoE2, maybe it's worth looking into here. Again, this is only if the above is correct.
Maybe it's not?
Honestly, the lack of a release date makes it hard to frame a lot of these discussions because we don't have any place to start in terms of what we know about the game.
