1) ...that the original version of this game heavily influenced the development of Coup. This game looks even more compelling to me, though.
2) ...that this game will see expansions if it sells well. I have seen the rules of the original game and one change I can see from the news article is that, when investigating an opponent, you only have to choose between 4 cards. This rules change would allow FFG to release more possible roles without the investigation becoming more difficult. I'll even go out on a limb and bet the expansions will be standalone i.e. Lost Legacy style. Why not?
Speculation is so much fun
