In an email today announcing availability of Firepower & Dr. Dude on mobile, the Pinball Arcade folks give the following hint about the next table pack:
"One new table has a connection with an area of the country we’ll be visiting next month. The other table is a re-release, and is based on a specific location somewhere completely different."
Next month they visit both Texas Pinball Festival and Midwest Gaming Classic. Anyone want to hazard a guess as to the games?
