The GWT release date has been pinned at "before the end of the year 2009". We are currently busy creating the modular structure onto which we will have 2 technologies to create user interfaces from: Dojo (Ajax) and GWT. Although this modular release is almost there (this will be 1.5.0), it will at first only contain the Dojo user interface. The GWT will be added in what we are now calling 1.5.1 (end of December). We are actually getting extra help to finish this, as other companies are also very eager for this GWT version, so this release date should hold. Note that when we first release GWT, it will be an unstable release (because it is a first release), but the API's will be stable, so you can start working on it already.
