I think a new 12-9-6 layout Navi is highly unlikely any time soon, given that Breitling are currently moving towards using the tricompax layout (i.e. 3-6-9) B01 calibre in the Navitimer.
I think you will have to look at pre-owned pieces if you really want that specific layout on a Navi. Check out the links here to see pictures of the various models over the years to see if there's one you specifically like -
