Things are bit crazy around here getting ready for JBoss World, and JUDCon in Boston, so we have not had time to get the roadmap nailed down and posted yet.
JSF 2.2 spec is planned to be released at the end of this year, but were not going to wait for Mojarra and MyFaces to support it before having a release.
I think the best approach for pushing RichFaces forward is timeboxed minor releases. A 6 month box is likely long enough to get cool new features in, and short enough for everyone to know the next release is not too far away.
That said, RichFaces 4.0.0 was released at the very end of March. This means for our planning ( which will kick off in earnest after JBossWorld on the dev space ) we'll be using an October boundary.
Hope this helps, and hope to hear feedback and comments for the release from anyone :-)
Thanks for your reply Jay!
