Lots of new information in this post:

The Adventure Board Game System is where many of the miniatures come from that we use, so I'll likely grab this on launch.
Now that we understand more of the AL I wouldn't mind playing though this adventure path as a player. To be fair I am rushing some of the material for our campaign right now and could use a good deviation if anyone is willing to DM something new once it is launched.
