Will the rest of the map in WH3 eventually be available, or has the upcoming 40K game killed this concept off?

I just wanted to ask, especially after the upcoming DLC is out, or have they mentioned this at all whilst promoting the upcoming DLC.

Also, everyone was hoping that Cathay and the possibility of the Monkey King being added would make this map space being finally used and available to play in, but so far nothing has been said besides from some hints in loading screen texts.

Has there been any other hints towards this either as I don’t think even the Tiger Warriors and Bashiva made any reach towards this empty land, especially with how cramped space can be when playing Immortal Empires.
