As Niburu said the new Fiesta is on sale very soon, Ford is now taking orders for it. As for the ST version probably the later end of next year maybe???.
I was at the London Motor Show last week and saw the Zetec S and Titanium versions of the new Fiesta. REALLY nice!!!! Personally I think the interior is way better - quite impressed.
I work with Ford on some of my projects so will see if I can find out about the ST release for you.
there are still no plans as yet that there will be a new ST next year.
