Why do XB1 game cases not list the resolution on the back?

They all output at 1080. That's why.

We already know that's not true, and so what even if it was? Every PS4 game (besides 2 apparently) does 1080p, and it's on their cases clear as day.

As you can see. The ps4 cases just listed the supported output and not true resolution and only bother listing 1080p. So microsoft could have done the same thing and just said everything has 1080p output as well but just chose not to. Can we stop grasping at straws now.
