Yup, they will be included in either in the "Civilian/Traders" pack or "Ulawful factions" (depending on which pack will need more bridges). What troubles me is that BHG are changing their models from time to time. If what they have now is what will remain would be great.
There are no plans to change the current BHG/APM ships (though personally I'd like to see a new Orca model)
