Excellent, I was thinking about the additional bits (primarily maps, though I prefer to run narrative encounters and leave minis to other games).
Well, the Missions themselves will have maps (or not, depending), but probably won;t always conform to the maps in the Toolkit.
Welcome to the 6th World events will have copies of the Toolkit for the GMs to use, including the maps.
Booth Demos will use miatures, mainly because minis are dynamic, they draw attention, and they make visualization easier for new players. Plus we have a nifty Warehouse dio that John Schmidt made for us this year. And yeah, probably won;t need the screen.
