BMW singed a deal with Nokia (parent co for Navteq) for their next generation Nav. So whenever the next, "next generation" nav systems comes out it should come with the Navteq. I think the new next gen like the one on our 2013 F10's will see an update of adding in a touchpad.
BTW - I for one am happy with the 2013 Nav. :-)
