They keep mentioning fall with a potential limited theatrical release. Seems to be pretty firm as it's getting mentioned in upcoming WB DVD releases now too. I'd expect something to be announced at the Comicon in San Diego this year.
A quote from Ridley stated that they were opting to try and get it into Venice film festival per this quote from Ridley in Total Film:
RS : It's finished. a five disc set in a Deckard briefcase comes out in the autumn. We've got a reconformed, state of the art digital print, which we haven't really had for about 15 years. It'll probably be shown at the Venice Film Festival.
