I think the next X5 will have that same "numb" steering feeling as the new 5 series. One of the reasons why I didn't get the F10 and chose the E70.
All the F series seem to have that driving characteristics. At least to me. So I. Am not looking forward to anymore new BMW's for me. I may move to Audi or something else in the next 3 years.
