perhaps your answer can be found in the first line of Barbaras
message. let me quote it:
"> On 4 February 2008, IANA will add AAAA records for the IPv6 addresses
of the four root servers whose operators have requested it. "
.... for the four root servers whose operators have REQUESTED it.
e.g. the other operators have not requested AAAA records be added
for their servers.

apologies for cross-posting...
On 4 February 2008, IANA will add AAAA records for the IPv6 addresses
of the four root servers whose operators have requested it. A
technical analysis of inserting IPv6 records into the root has been
done by a joint working group of ICANN's Root Server System Advisory
Committee and Security and Stability Advisory Committee, a report of
which can be found at http://www.icann.org/committees/security/
sac018.pdf. Network operators should take whatever steps they feel
appropriate to prepare for the inclusion of AAAA records in response
to root queries.
More information will be posted to the IANA web site during January.
