The 'Titanium' model is the replacement for ST in the MK4 (As well as being faster than it's V6 powered predecessor, it also is more powerful), so I should think this will be the same model line up for the MK5.

The MK5 looks like an Aston from the front and no doubt there will be a Titanium, very surprised if it has the Volvo 5 pot though (Unlike it's predecessor) as Ford has now dropped this in favor of smaller 4 pots, incidentally fact Ford no longer have any ties with Volvo.

For example both the Current Focus ST and the next Focus RS have 4 pots.
