I can see the PC having to chop down trees to build a house in TES VI, but I doubt you will be encouraged to gather useless garbage like in Fallout 4. You normally have a lot less "clutter" in TES games. I wouldn't be surprised if we saw a return of the weapon crafting system however, smelting iron swords to improve your left pauldron. That would be one positive change to take from Fallout 4. It would give an alternative to loot hoarding and selling it evenly among the vendors in the major cities for gold that you can't really spent on anything worthwhile.
