Quoted from PtownPin:.almost zero chance they shipped NIB games from Jersey to Chicago
Setting aside the possibility that the machines were moved to Illinois when the rest of the factory was loaded up in trucks, it is not uncommon in this industry for games to ship from one pinball warehouse or company to another for inclusion in a container going overseas. If this container is a mix of Wonka and GnR, then at some point those games needed to be in the same place. While not likely in this case, there have certainly been containers going overseas with games from 2, 3 and possibly even 4 manufacturers on them.
