what is current status and likely future of turbine ?

We have built several projects in the past using turbine.
We are beginning a new project and trying to decide whether to
use turbine or try something else. 
We are a little concerned that turbine is dead or dying from lack of 
community.

My questions:

1. When will turbine 2.3.3 be released ?
2. Is anybody working on that release ?
3. Is there any active work on the turbine code base ?
4. If there is no work, is that because it all just works or because 
everybody has abandoned turbine in favor of something else ?
5. Probably asking the crowd since the people who voted with their feet 
have stopped listening, but what do you suppose
people have adopted to use instead of turbine ?  is it VelocityStruts ?  
is it Spring ?  Others ?
