I've seen some reports in Auto Express.
A RS badged mk2 Focus would be cool, but if they bring it out now it will over shadow the ST just like the mk1 RS did to the ST170.
It wouldn't surprise me if they did, after all the RS has about 45bhp over a st170 - so a mk2 RS would probably have about 100bhp over it.
We'll have to wait and see.
