So if no one has seen it on Wyrd's website, there will be a summer campaign starting tomorrow June 15th, 2012 and lasting until who knows when. I can guess, probably sometime in August.
From Wyrd's Website:
Dead Heat: Worldwide Campaign
Attention Citizens of Malifaux the following is an important message from the Breachside Broadcasting Company:

No rules or anything yet, but apparently that podcast is going to be doing weekly updates on the campaign, and I've heard rumors that they will do location specific things. Like if you want zombies to eat them, take over downtown with Ressers.
Looks fun, 0 competition because there is no cost and no prize, just seeing if your faction gets on top.
