As far as I know, all current armor/clothing items (minus plant fiber gear) will be replaced by outfits, and the plant fiber set will become an outfit. So yes, those clothing/armor items you mentioned will probably be replaced.
Either the night vision goggles will become a mod (although MM already confirmed a while back that this will not be happening), or they'll be a part of a stealth armor set, if not removed entirely.
I wonder what will become of the Needle and Thread book series though.
Going on a side note, but speaking of book series, I'd like to once again outline how almost pointless it is to lock the M60, steel club, and steel spear schematics behind higher gamestages if you can just find the books to craft said items at any point in the game.
