It looks like some big changes are coming to Google Play. In an APK Teardown from the folks at Android Police, they discovered some pretty massive changes coming to the service. The first one involves a more heavy implementation of Google+. It looks you will have to have a Google+ account in order to leave app reviews on Google Play. This means when you leave a review, your name and photo will probably appear next to the review. It also looks like some tweaks are coming to the way you share apps, probably in form of sharing your reviews with Google+ circles.
