button to turn off TC and ESC, like the Focus ST would be fantastic!
As for wide rubber, I doubt they will go any wider than 205mm wide tires the EU Fiesta uses. I run 215's without issue, but I don't see the factory opting for those since there are probably cases where the 215/40 17 with a certain offset would impact the inner fenders.
Overboost would not be a big deal, but if the Fiesta ST had it, I would be using it all the time. I would assume the ST will be untunable, just like the regular Fiesta, so the overboost option would take the place that a tune could do.
