In my mind it never was a transition plan. It was, and remains,
a co-existence plan, which will go away when co-existence
is no longer needed.

One thing that we demonstrated very convincingly last week
is that there are enough legacy devices and applications in
existing user hosts that the co-existence plan is still needed.
(And, BTW, we demonstated it for user hosts belonging to
relatively sophisticated users.)
