Put it through google translate, so there might be some inaccuracies, but sounds good to me:
The inventory is divided into your backpack, equipment and cyberware. The game allows you to wear clothes as headgear, on the face, in two layers on the upper body, as pants and shoes.
There is also a separate field for outfits, which probably correspond to a complete look made up of several associated parts (perhaps a suit, for example).
Cyberware mods or fragments also seem to be part of the inventory screen and here I see four free slots.
I can currently see three slots for weapons that can be equipped.
With Quick Access you can choose a gadget or a consumable item, which can then be quickly selected on the D-Pad
As far as I can roughly estimate, the inventory is visually represented as an area of 10x12 fields. With the items you have the filters for all objects, weapons, clothing, consumables, quickhacks and job items.
The maximum number of items you can carry with you naturally depends on the weight. The size of the icons in the backpack, however, seems to represent the actual size of the objects: an inhaler has one field, a gun perhaps two fields.
1) Weight is a factor
2) Realism/immersion element is introduced through the backpack (as opposed to magic pockets)
3) 3 equipped weapons on hand
4) Attire is divided into 4 slots: head, pants, and 2 layers on the upper body
Points for CDPR.
