Zineb Ait Bahajji from Google announced on Google+ that they have launched the new Search Analytics report within Google Webmaster Tools for a subset of webmasters using Google Webmaster Tools.
To see if you are part of that launch, go to Google Webmaster Tools and if the Search Queries report was replaced by Search Analytics, then you are in.
I covered these reports in detail when it was first beta launched under the name of Search Impact report, so review it there if you do not have it yet.

We've made the new Search Analytics report available to a random sample of our users .Some of you might notice that they now have access to it in their Google Webmaster Tools account, under Search Traffic in the left navigational menu. If you're among the new testers, I hope you'll enjoy using the report. Let us know what you think in the comments,
PS: The new report currently has less than 90 days of data, but it will catch up in the next few days
Do you see the new report, it should totally be superior to the old one.
