Any word on the date for the expansion? I'm very interested and would love to play with the new modes/mini's.

Last update was that the game's on the boat as of 2016/12/10. On the boat means 4 to 6 weeks (in general) before it reaches their warehouses. So, it should land in the US somewhere between now and the end of the month. Then it enters the distribution chain and it takes 10 days or so to reach retailers. So, my guesstimation is hal of February the game should be out

Yeah. It does seem like it has been on the boat (raft or canoe?) for way too long. I hope it still gets released soon..
