The demand is for the 3GPP trials and they are in Europe and Asia. They are

It was always late 2002 but trials and interoperability will start now.
Delays are not official but I agree most likely.

True in that context.  But that was not my context.  My context was the
invesment in stacks is real.  A change will take time to absorb new features
as it will with anything new from any IETF new IPv6 work.
