Rollouts can take quite some time, up to several weeks. It's possible it just hasn't gotten to you yet. Has your Google Play Services updated yet? My Nexus 7 is currently on 6.1.83.
You could consider uninstalling all Google Play Store updates, then see if that triggers the automatic update.
If you're really concerned about it you can grab the APK from somewhere online and install it manually, but there's no harm in waiting. If you want to try a middle road, tapping the version number in the Play Store settings should force an update check, but if it hasn't rolled out to you yet that may not work.
Google play services version is 6.1.83. I uninstalled all app updates to bring the app version down to 4.5.10. But then it only went back up to v4.8.20 and before this all happend, I was at v4.9.13.
Question: 1, What is APK?
2. My android,.. Motorola RAZR has been sooooo slow in anything I do. I've deleted some programs that don't work right or that I don't need...how can i speed up my phone? Any help is appreciated. Thanks!
1. Apk stands for android application package.
2. Try doing a factory reset on your phone. Or, see if there are any software updates for you phone or any apps that you have installed.
