We are using Market Press for an Etsy style multisite

We are using Market Press for an Etsy style multisite setup. Each site is an individual site, and we have no way of pulling stats from those sites so we can award highest sales, power seller etc... I know there was a Google Analytics option, but that won't work for us. I have read that you are adding stats capabilities for Market Press on your next update. Do you have a timeline of when that update will be?

Thanks.
