I think you're referring to n2668 from 2008, which concluded with:

        Recovering the Loss

    The largest potential loss in performance due to a switch away from
    copy-on-write implementations is the increased consumption of memory
    for applications with very large read-mostly strings. However, we
    believe that for those applications ropes are a better technical
    solution, and recommend a rope proposal be considered for inclusion
    in Library TR2.

That's not the same as saying that it will be.  We don't know yet what 
will be in TR2 as far as I know.  If you go to the working group's 
page:  http://www.open-std.org/jtc1/sc22/wg21/ you see a link to the 
draft of TR1, but nothing for TR2 yet.
