KD:M is quite the outlier, it appears head-and-shoulders above every other board game ever printed, ever, at least with regard to quality, design, art, etc., which affects things past simple availablility and timing. Like, somehow this guy has created the WoW of board games. Also, the prices of the original game skyrocketeted literally the minute after they began shipping. I don't expect anything too terribly different. As I mentioned, it's expensive (and yet somehow EXTREMELY popular), so people want it. If they can't get everything theyw ant from this KS, they may need to save up and buy later. Shrug.
All I can say is $1666 (plus shipping?) will be a zero-regrets purchase for me, as much as I've wanted the game ever since I heard about it ~5 years ago when the dude began talking about it. REALLY wish I had had the cash during the original KS.
