As far as I've heard there isn't a new P5 fro 2003 because they are just continuing with the same line. As for 2004 models, I don't know, haven't heard a peep.
the NEXT gen of them will be, or is at least SAID to be built on the focus platform....but what they will look like is still a mystery....that COULD be because they havn't even designed it yet! lol
