Does anyone have more information (rumors welcome) on this ?
If this is true and since it is a major upgrade (from version 2.09 to
3.0), a lot of commands must have been touched.  What I am concerned
is how well is the backward compatibility.  More specifically, will
my LaTeX files pass version 3.0 compiler without change ?  Will all 
the customized styles ever posted on this news group pass version 3.0 
compiler ?

It goes without saying that if too many 2.09 commands are obsolete
in version 3.0, it may as well be named NewLaTeX 1.0, not LaTeX 3.0.
I'd appreciate if someone can share a light of what's going on.
A things-to-do alike list is preferable.
