The diesel M Performance cars that have already been announced (M550d, etc.) have already switched to hydraulic power steering, and I hope they continue this with the rest of the M Performance cars. Hydraulic steering is something I consider a must-have at this point. Maybe in a few years the EPS systems will be good enough, but right now they aren't quite there. The hydraulic steering in my 135i is easily my favorite thing about it. I drove ~300 miles in our F10 this weekend and just now went for a drive in my 135i, obviously there are many differences between the cars but that steering really makes a difference.
To the people complaining about body roll, I'm glad the suspension is compliant. I don't know if you have lots of smooth roads where you live, but in my area all of the fun roads are very poorly paved and cars without a lot of suspension compliance are practically useless.
