Google Merchant Center Next added new analytics data to the Promotions tab/section. This shows you two new analytics charts including "Your promotions at a glance" and "Performance in the last 28 days." These are summary cards to see how well your promotions are performing in Google Search.

This report has gone through a few different iterations in recent months, with this looking like more of a final form.
Here is a screenshot of this:
