Nice research! Seems like a trend for everyone to criticize the steering feel of the newest production 3er...
as for the steering, I think it's excellent. I have the DHP and it definitely improves the feel over the standard sport suspension. Also much easier and livable for everyday driving, while still being very sporty when you want. I think BMW did a great job (aside from the steering vibration epidemic) and I'm sure they will continue to improve it as production years go by.
Enjoy your ride when it arrives!
