Since GWT is open source, Google 'dropping' it (many largish Google projects use GWT and they still commit code) is not the death knell for GWT based projects.

Since GWT is open source, Google 'dropping' it (many largish Google projects use GWT and they still commit code) is not the death knell for GWT based projects. For the same reason it is being actively developed and has a steering committee and regular participation of googlers. It is also 'probably the best cross-compiled JS framework in the world', to borrow a phrase from the beer industry. Full-featured and works today, not 'maybe in five years' which is what Dart promises (I'll be the first to jump onto it when/if that time comes).
