Charles Boyd added later on in the stream that they want to introduce same-sex romances for other vanilla companions when it fits in thematically with the story. He wasn’t specific on timing but it is definitely the direction they want to go in.
They also revealed details on a host of other features coming into Game Update 5.10 including sweeping Guild Changes and Improvements and a new PvP Challenge system that allows you to challenge others to private Warzones and Arenas.
