But are the members of the list aware of the only method by which LaTeX2e
will get chnaged from now on?

This will only happen if people such as the memebrs of this list
producing packages that implement such enhancements.

Yes: exciting, are they not?

How long is rose stem?

Much of the current work on TeX's sucessors is, in fact, development
of the current TeX (but what they have produced cannot be called TeX).

It is all (we hope) known to the LaTeX3 team and much of it pays
attention to what we think and to what goes onto lists like this one.

There has been branching, which has its pluses and minuses, but it
will be a Bad Thing if these canot be brought together again soon (to
some extent this convergence is beginning).  If LaTeX3 is based on
something other than standard TeX, we shall need to be certain that
this will be a system that is widely available, easy to install and
well-maintained.  Of couse there is a something of a egg-and-croccdile
situation here.

This is the latest published source.  I have no idea if it is good as
all I did was write it:

\item
Frank Mittelbach, Chris Rowley.
The \LaTeX3 Project,
Communications of the \TeX{} Users Group, 18, (1997), pp 195--198

No doubt there is proper BIBTEX version of this somewhere.

As a supported system, that depends largely on when we can get significant
person-power devoted to building up and using the LaTeX3 Programming Language
(hence my earlier message).

You could try SOOTHSAYERS-L or ORACLE-L (oops, maybe not:-).
