When can we expect new FATE music?

Every expansion brings a new battle theme for the outdoors, but we have the same FATE music since 1.0.

I'm sure many will disagree and would not like any new music, so perhaps there can be an option for these players to keep the same theme for all of thier FATEs for thier immersion.

This way everyone else can have thier FATE music updated to an OST more befitting of the expanion the FATE is spawning in, much like how the battle themes are updates with each expansion.

It might be tight to fit in with the 5 month updates but I hope the development team can find some time out of thier busy schedule to fulfil this request.

Thank you.
