Indeed. Another one is coming up I understand. Right John? ;)

GlassFish is in its second major release and third year of supporting
Java EE 5. EJB load-balancing is there for all versions of EJBs, 2.x
and 3.0.

The comparison is between v2 and v3 "Prelude" which is essentially a
web container at this point.
If EJB container is what you need, stick to v2 until v3 ships with
full EE and clustering support.
Many people are excited about v3 (modular architecture with fast
startup, load-on demand, small memory footprint, etc...). You may not
be in that category which is fine. v3 is not a replacement for v2 just
yet.

thanks. I'll pass this along to the documentation team (note we have a
dedicated docs_at_glassfish.dev.java.net mailing list set up for such
feedback).
EJB clustering is very important de many. It's always hard to strike a
balance between the many features of a product.
