I see this ending up back before SCOTUS rather quickly... the District Court will find that anything Census says is entirely pretextual, and SCOTUS will have to address this one more time.
Roberts really made this way more complicated than it needed to be by trying to straddle the fence here.
2010 census forms have to be printed soon.
SC is done for this session, i.e: NO question re citizenship on the 2010 form.
Big loss for U.S.!
