I know some people have used a USB keyboard on Xbox, but now they've announced keyboard and mouse support is coming, will we gain full keyboard and mouse support from DTG?(including things such as scroll to zoom on the mouse) Fingers crossed it's in a future update, along side the many fixes for broken stuff.
This would be one of the titles where it would make sense to have mouse and keyboard support. Since the keyboard is already working in some ways I hope they add both (m+Kb) native into the game when the feature launches out of preview.
