Google has a problem in the form of two platforms: Chrome and Android. I believe they will merge. Android will be Web.

- MobileChromeApp[1] converts Chrome Apps into Android apps. Developed by Googlers.

- Web Components enable modular, re-usable code. Polymer[2] is backed by Google.

- AngularJS[3] is a modern UI framework for the Web and is backed by Google.

- Dart[4] is a new language, with tools and libraries, for scalable Web app engineering from Google.

- AngularDart[5] is Angular on Dart.

- ART[6] is a new Android runtime that leverages LLVM, opening the possibility of offering alternative front-ends for Android other than Java.

- Sundar Pichai runs both Chrome and Android.

- The rumored Hera project is supposed to marry Android to the Web.

Dart + Angular + Polymer + ART = new Android Development

My bet is that the future of Android is Dart, Polymer, and AngularDart.
