I still only have Max4.2 at home. Just upgraded to Max2009 at work. The only thing that is the same is the bugs and poor reliability, heh.

Sadly, looks like CAT ( http://www.softimage.com/products/cat/ ) is being pushed to take over the field in place of Biped. GREAT rigging tool, but the animation system is HORRENDOUS, IMO. Needless to say, life at work has been painful with CAT. Totally not sold on it.
