Yes I have discussed it on other forums a lot. I think it came up in this forum too a long while back, but no one seemed to be interested in a discussion.
I continue to be extremely sad and disappointed this game was canceled. I have zero doubts it would've been a fantastic game. There is an interview or video out there somewhere in which J.E. Sawyer discusses the vision and plans he had for the game, but he also emphasizes there is zero interest within Obsidian or himself to resurrect it.
The main takeaway point for me is exactly the idea of the game being set in the Dalelands. I would soooooo love an FR game that is NOT set in the Sword Coast or Icewind Dale or Neverwinter areas. There are so many awesome areas in the FR setting; why do we keep having to play in the same damn areas again and again?
