they are designing most Performance models to accept xDrive which does not have EPS so I would imagine to save R&D they would develop one rack and that would be the hydraulic one.
In my talks with M engineers, they felt EPS sacrificed too much feel for the "limited efficiency gains" and they dod not approve. They did more with weight savings than the EPS did to save MPG. (for what it is worth).
Just to be clear, what you've said about xDrive not having EPS doesn't hold true for the F30 (and likely F20) which will be the first xDrive models that have EPS. Personally, I doubt BMW will switch to a hydraulic rack just for the M Performance models as sales are likely too low to justify the expenses. And yes, the next M3 might have EPS too.
