I don't know that you can expect much for changes on 4120 in the near future other than model # changes to be in line with their new worldwide model # scenario that references gross hp. The 4320 and 4720 have already changed to higher hp units (due to govt emissions) and have neat options like e-pto. Otherwise maybe see something for 2010, expect for dealer people to know more about this after the btl which starts mid October.
