Will the Marketplace Generate Sale Metrics?

This applies to the general marketplace and specific marketplaces like the one for Unreal Tournament. I’d like to see what is selling and what isn’t selling so well. Obviously detailed reports would probably be better reserved for private viewing of the original developer. I’d like to see something similar to Google Play where they list how many downloads took place. Some sort of rating system is needed as well. Simple items like hats can just be sold by an image showing just what it looks like, but for more complex items, from UT weapons to complete UE plug ins, we need to know what works in order to buy and sell on the marketplace.

EDIT: I see there is a rating system in place for the web based marketplace. Will that be implemented in the desktop store?
