Beta client datamine (build 1.60.1.69876) gives boss-encounter counts for Hall of Thanes (4) and Ruins of Lordaeron (7) and Excavation Site: Wetlands (4) but no names for any of them - confirm via further beta datamining or player reports once the beta's sub-30 content is actually run (beta cap reached 30 partway through the Sept 17-Oct 21 window).
