From their announcement:
Advanced Squad Leader is back. All veterans and curious new recruits are welcome to come clash the cardboard. Play open games of what you want, with who you want for as long as you want.
Its not just ASL either. We have moved the entire board gaming area to another room where there will be more space, and we’ve expanded to all day Friday of the convention weekend. Get into town, unpack, then setup your games.
