It has superior features, but its current implementation is much
slower and there is a HUGE body of existing code that would need
conversion (a lot of that is automatable), including most uses of the
logging module. % formatting is also familiar to anyone who uses C
and C++ on a regular basis.
as martin said, both will exist for a long time.
