I also got the impression that it was going away.  PEP 3101's abstract
says:

    This PEP proposes a new system for built-in string formatting
    operations, intended as a replacement [sic] for the existing '%'
    string formatting operator.

Under "Backward compatibility" it says that both systems can coexist
"until it comes time to deprecate the older system".
