The biggest reason likely has to do with the way internally geared hubs work. Because it is a planetary gear system, it depends on a completely straight axle. If you bend an axle on your Alfine or Rolhoff, not only will you not be able to shift but your wheel won't roll at all. Bike manufacturers aren't likely to spec an internal that is even remotely likely to seize on the trail.
If your version of mountain biking involves lots of doubletrack or flowy rollers, go right ahead and retrofit your hardtail. If your typical ride is a little more jarring, with drops and square-edged hits, wait for the unobtainium-axled version.
For full disclosure, I am a huge fan of internals. I'm still thinking of putting an Alfine 11 on my Kona Unit for commuting, winter XC riding and lighter xc fare. I wouldn't put one on my five inch dually.
