a color 13.3" eink tablet

I would like to buy a 13.3" tablet with color screen. I see Mooink Pro 2C just released one early this year. My main usage would be PDF reading, note annotation, and use as an extended monitor for my windows PC. The Boox tab X fits the requirements except the screen is not color. Boox Ultra C pro only has 10.3" screen.

I wonder if a Boox tab X Color will be released soon?
