Why does the back of the case for xbox one games doesn't tell you what the video output or resolution of the game? Is it 720p, 1080p or what?

I just looked on the back of a few of my 360 games and they all say the same thing, HDTV 720p/1080i/1080p.  Maybe they got sick of putting the same thing on every box.
