Totally agree. GWT 3.0 without RPC would be GWT 3.dead for many of the
current GWT developpers,
For me GWT is "Web development based on Java expertise, with practically no
other technology implications". Extremely powerful and pleasant. Seems that
GWT 3.0 is announced as "no more GWT":
Our plan will probably to stay with 2.8... But will 2.8 ever be released
??? Developers have been waiting for it for so long... GWT's communication
is very strange and paradoyal.
