Just curious - when did you order your game? I ordered mine in early June and was hoping to make the fifth edition, but I haven't heard anything about shipping.
I'm waiting too, order placed in April. I don't think they send notifications, but I'm encouraged by this from splottershop.com:
IN STOCK NOW!
Food Chain Magnate is our 2015 release. The 5th print run is in stock right now. We have shipped all individual orders-- note that it will take some time for them to reach you if you live faraway (such as in the US).
