Vaadin is hosting a GWT conference. In fact two: the conference is being held twice, once in San Francisco (started now) and once in Frankfurt (next week, sold out).
Ray Cromwell just held the keynote on the future of GWT, and there is a lot to come.
- better JS interop
- full Java 8 support
- faster, incremental compilation
- better SuperDevMode
- much much more…
The next major release (3.0) is planned for Mid 2014, one year after version 2.5
