Xbox allowing keyboard use.

Will this be available on this game in the future on Xbox?

Unlikely they will have direct keyboard/mouse support. They said when they did the console version they didn't want to support controller for PC as they didn't want those playing alongside each other and the code base is different.

I believe the Titan One will let you use a keyboard/mouse as a controller, but I have a feeling it works about as well as apps that let you use your controller as a keyboard/mouse, but maybe that will work for you.
