Well now, I am glad I got mine with the MT when I did if it is gone in MY15. I ordered it back in March and just got it last week but so far I am very happy with it. My mileage in mixed driving has been around 27 mpg per the lie-o-meter in about 250 miles, so I haven't had a full tank through it yet to see how accurate it is. I went to the Fusion from a VW Jetta with the TDI with a MT so anything is going to have sucky mileage after driving that. Like the OP I am not a fan of the electronic park brake, I wonder about the longevity. However, the nice thing is it will automatically release when you let the clutch out.
Now if only I could find a boost gauge for it!
