From Ted Neward at TSSS:
Linda is the Group Lead for the EJB 3.0 Expert Group, and she presented a basic overview of the current mode of thinking for the EJB 3.0 working group. If you want to get a jump on what EJB 3.0 will look like, pay attention to three things: JSR-175, Hibernate, and Spring.
Jason has some words on this as well.
