Google 在五月时的 Google I/O 大会上公布了 Android Wear 2.0，随后亦推出了 Developer Preview 版本。但 Google 最新就表示会延续 Developer Preview 至 2017年年初，意味正式版本也要待至 2017年才推出。
We’ve decided to continue the preview program into early 2017, at which point the first watches will receive Android Wear 2.0.
Google 刚推出了 Android Wear 2.0 Developer Preview 3，并同时透露从 Developer 社群得到的回响，决定将 Developer Preview 延续，在往后还会推出多一个 Developer Preview 版本，之后才会将 Android Wear 2.0 平台转交给 OEM 厂商应用。
Android Wear Play Store
至于最新 Android Wear 2.0 Developer Preview 3，就加入了 Google Play on Android Wear，用家可以透过手表直接浏览找寻 Apps 安装，而且用家可以只安装 Watch App 在手表上，不用同时安装在手机上。
third developer preview of Android Wear 2.0 with a big new addition: Google Play on Android Wear. The Play Store app makes it easy for users to find and install apps directly on the watch
If users want an app on their watch but not on their phone, they can install only the watch app. In fact, in Android Wear 2.0, phone apps are no longer necessary. You can now build and publish watch-only apps for users to discover on Google Play.
