Fujifilm registered a new trademark for the name X-H (Fujifilm X-H). The filing clearly describes the X-H as a digital camera:
Digital cameras; lenses for digital cameras; digital camera flashes; cases adapted for digital cameras; straps for digital cameras; image sensors for digital cameras.
This could be a new line of cameras coming soon relating to the other filing or it might just be a place holder for the time being.
