Holy shit. Google has started pushing out the Play Store 4.0 update, which was leaked only a couple of days ago courtesy some Googlers.
Google is saying the new update is focused on being clean and fast, helping you discover great content easily. Right now, the Play Store client is ugly, and I say this is the most kind manner. If you have a phone or a tablet, you should look out for this. The update has started rolling out for devices running Android 2.2 or greater, and will reach everyone in a few weeks.
Don’t worry, someone will extract the APK and we all can have it sooner, if anything.
