I spoke to some Sun officials about this on a
Java conference in September, and they said they were going to alter the focus of the SCBCD away from entity beans "in the next revision, which they might be planning on doing something about in october or so". I.e. they will do something, they might already have starting by now, but not going to be available until next year. Sometime. Maybe.
I for one have decided not to take the SCBCD, as I don't want to study EntityEJB relationships and stuff just for the exam, as I won't ever be needing it. I might rethink after the new exam comes out.
