Please stop saying that there won't be.

I guess differently.

I'm convinced that there will be a migration path.  I don't know if it
will be painless or automatic.

It may take the form of Zope 2's lower-level infrastructure being replaced
by Zope 3's.  I think this is entirely possible and would constitute a
real migration to Zope 3.  It's very possible that there will be a
Zope 2 in the future that supports Zope 2 paradigms and Zope 3
paradigms simultaneously.  This would look very different from many
"pure" Zope 3 applications, but perhaps no more different than a
number of sucessful Zope 3 applications such as Schooltool and applications
being built by Canonical.
