Google has updated its Play Store's website to more closely align with the design features of Google Now-style cards, which actually makes the place look a little more organized and much more like the official app. While these updates are cool and certainly needed, the most notable change is the inclusion of apps for Google Glass.
The addition of Google Glass compatibility checks were first spotted by Nicolas Gramlich. It's no surprise that Glass has shown up on the Play Store as Google likes to streamline their device management. Website androidandme.com has also posted a screenshot which appears to be of the official Google Glass app for Android. With these hints, it appears that Google Glass users will officially have access to the Google Play Store any day now.
