EB1 (for A, B & C) "Filing Date" is current i.e. you can file any time.
But "Final Action Date" using which Immigrant Visa, i.e Green Card, is issued has retrogressed to Jan 2010.
Moral of the story: EB1 485 can be filed currently, but GC will not be issued until Priority Date is current (expected on 1 Oct 2016)
