Open Document Format -- Successor to XHTML? (interview with Gary Edwards)

There's an interesting interview with Gary Edwards, one of the
leaders of the team developing the Open Document Format (used in
StarOffice8, OpenOffice2, etc.) See:

   http://madpenguin.org/cms/html/62/5304.html

One comment Gary made was particularly bold:

   "...OpenDocument is now before the ISO (International Standards
   Organization) board for ratification. From there, there is no doubt
   in my mind that OpenDocument is heading to the W3C for ratification
   as the successor to HTML and XHTML."

Any comments/thoughts on this particular statement by Gary? And any
comments on the remainder of the interview?
