So I've been trying to go back in the posts here to see when info started being announced on Cornucopia (the previous small expansion), but the posts here only go back to June 2011 (i.e. just in time for Hinterlands, and pretty much exactly when I started getting on here anyway). Dare I go over to BGG to check?
EDIT: Checked BGG. Apparently the first spoiler happened in April. I don't know if I can wait that long...
