I think the future will basically be manufacturers selling directly to customers like Tesla does with cars, no more margins for middlemen or very little. I remember working for a perfume store that closed up shop 8 years ago, basically the supplier that we were buying form started his own website and selling for same or less than we could buy it. Eventually even the supplier went belly up as the manufacturer started selling direct and still does to this day.
We can draw parallels between EVE's official alibaba page which lists cells for less than any of the resellers
