No idea what will happen in the future but I wouldn‘t wait for that because it could take a long time and so far I haven‘t heard of a patch being in the works.
However, if there was one, it would probably focus on bugs, not on scaling up certain weapons and armor pieces. In TW3 you get so much gear along the way, that is not really necessary. And some pieces you can craft at a blacksmith, if you have the diagram.
