I am not shure we even need a hires texture remake. If we zoom in on our own faces/gear i see no pixelation. So i would guess they are fine.
Only in some cutscenes we see bad pixelation on closeup gear. My guess is they have a bug that needs to be fixed. That or some NPC gear is made lower res then our own gear. If they then decide to have a closeup in a cutscene i find it a very bad choice not to make the npc gear higher res.
Second place we could use higher res textures is the ground in some places.

To sum it up we could use some higher res texture in some select places but we dont need them in general.
