Something that stuck out to me, given that people keep asking why they haven't released the relic grind yet...

Larger projects such as streamlining of the storyline and adding flying to A Realm Reborn areas can take anywhere from nine to even twelve months, where our staff find time in between working on core patch content to get them done. Some other examples include the World visit system, cross-World party finder, and the Bozjan Southern Front (coming in Patch 5.35).
Unless it's been confusingly translated, this seems to imply that the Bozjan Front is "non-core patch content" that they work on when they can find the time after everything else is ready.
