For the company I work with I have to plan the transition from a custom build Java EE stack (Tomcat with manually added libs for JSF, JPA, JTA, etc) to a full Java EE (5) AS.
I'm considering Jboss 5 AS as one of the possible options. Unfortunately I can't seem to find any pointer as to when the final version of it will be released. As the evaluation and transition is likely to take quite some time (the existing application is rather large) it would help a lot if I approximately knew when a release could be expected (e.g. like first or second half of 2008).
My experience is that JBoss will not publicly estimate release dates; they just announce when they happen.
