As it seems, Housekeeper's announcement only referred to the new line of models.
So far, updates are only available for North America (NA) and the Commonwealth of Independent States (CIS).
Edit:
As OphReader has pointed out on the German sub-forum, it's worth twiddling the filenames in the links. Thus, firmware versions for 902 become available, too, as well as the North American firmware version for 602:
