Hi HX,
I mean only that at jboss.org you have Projects which can eventually lead to Products. The idea is that Red Hat picks and chooses the Project elements it feels it can offer support on within the Product(s) it will offer.
jBPM version X is always here on .org an unsupported Project offering.
The jBPM Community Project members can work on jBPM 4 (I assume you all will, as there has been lot's of interest posted here lately so why stop working on it). The code base is GPL, it is freely available and I am assuming anyone with a bit of competence and interest will be given the chance to commit to the project.
It is all open source here at jboss.org, life always will and can go on....
