"borrow"?Great idea, but I don't know that Abrams would want to borrow from A New Hope.

The new Bladerunner is really, really, good.It is hinted at by the emperor himself (though perhaps not clearly explained). This means that both the emperor from RotJ and senator Palpatine would have been clones. But considering how busy the movie is, I'm not surprised many people missed it. At that point I think the majority of the audience is tuned out or only paying half attention.
Unnecessary? Absolutely. But the 'real trilogy' was already wrecked by the prequels, in which Anakin is an unlikable a-hole who murders children... unless you simply ignore those movies happened, in which case the original trilogy remains a timeless classic.
Bladerunner is also still a classic movie, despite the recent sequel now deciding that Deckard was a replicant all along, only because it was a popular fan theory (there's nothing in the original movie to indicate that this was the case).
John Carpenter's the Thing is also still an awesome movie, despite the awful CGI-filled prequel that we got a few years ago (which also introduced a lot of plot holes).
Those things don't affect me that much.
I'm going to quote Ridley Scott on this one, when asked if Deckard is a replicant:
"If you don't get it, you're a moron."
Ridley Scott is cantankerous about this movie for obvious reasons. I don't think people are morons for either thinking there is ambiguity, or even preferring that there be ambiguity, ESPECIALLY given the issues with the original theatrical release. But I also think that the quote encapsulates the director's feelings regarding the issue- Deckard is a replicant, and it was always meant to be clear, even if it wasn't spelled out in dialogue.
(If nothing else, the inclusion of the unicorn dream cuts off any possible alternate meanings).
Not that I know of.
