West End also informs us that they are producing with Amarillo Design Bureau a D6 System book for Star Trek. The volume will be called D6 Prime Directive and is expected out in July. Subsequent sourcebooks are possible, although specifics are not fully confirmed at this time.
edit: apparently this is based on the Starfleet Battles universe based on discussion elsewhere
