As long as we are in EA, features can be added; after that, its another story; I quoted you as duels is pretty possible, in the quest spy among us, you actually duel the NPC you pick out. So its just up to TW to add the event option somewhere.
If this is a feature complete game, I'm pretty sure nobody will buy it at release. Steams scores will be killed, doom. but it's not feature complete; and referring to posts of a developer who is not perfect English, and drawing conclusions from it, is ... sad. The result will be no other employees will join the board and updates will come through the normal (slow and vague) channels.
