We still have 1/4 of shb in front of us.
Don't expect the new add on within the next 6 month.

There is content waiting for us.
I still have hopes in bozjan and the BA like dungeon (BA is something I still do regularly)
There is a potential next ultimate.
Another trail and more story.
Blu mage will get more stuff to do and ishgard will be finished.
I expect more qol changes and maybe a first step to bring datacenter closer together.
Small changes will happen that opens the way for new stuff in the next expansion.
