What we will see is a drop in demand for certain items and an increase in others once chapter 2 comes out.
If there are new skins for weapons (which there should be from the contest they just had), new mods or better type of modding on the new weapons, there will be a high demand for those of course. Once the novelty has worn off on looks, it will go back to stats and the high prices we usually see on those items.
I suggest saving your money, farm for the new weapons (when chapter 2 is released), and make your own choice. Simple enough.
