I can't believe I'm taking Rick's side here, but the docs do say:

"Note: The formatting operations described here are obsolete and may
go away in future versions of Python. Use the new String Formatting in
new code."

http://docs.python.org/py3k/library/stdtypes.html#old-string-formatting-operations

I consider that a statement of deprecation, even if it doesn't use the
term explicitly or describe a definite timeline for removal.

Cheers,
