Providing there is more viable images, I remember reading a Bad Astronomy blog where Phil Plait explained that the Hubble website retains images taken by the telescope for a year to study by scientists so that the website doesn't get overloaded and so that scientists have enough time to study what they shot. After a year, they release the images to the public.
You'll have to search through his old logs to confirm, but that's the gist. Either they're studying it before making a pronouncement, or there's just nothing viable.
