Interesting, according to this new paper:
http://arxiv.org/pdf/1401.5761v1.pdf
classical black holes may not actually exists. Quantum mechanics prevents it, as I understand it
----
I was left with the question: Is the conservation of information a quantum effect?

For the benefit of any others who, like me, struggled with that article, here are a couple of more "hitch-hiker" friendly links.

Weird stuff, remember when the 'firewall' thing first came, and now it seems as Hawking wants it gone :) The worst thing about this kind of ideas is that there is no way to test them, that I know of? So we got a hypothesis building on another hypothesis building on ...
Although, SoulSurfers idea of there being no dimensionless center of mass now seems as a possibility for Hawking too I gather?

Matt Strassler has some interesting comments.
“Media absurdity has reached new levels of darkness with the announcement that Stephen Hawking has a new theory in which black holes do not exist after all.
No, he doesn't.
First, Hawking does not have a new theory... at least not one he's presented. You can look at his paper here --- two pages (pdf), a short commentary that he gave to experts in August 2013 and wrote up as a little document --- and you can see it has no equations at all. That means it doesn't qualify as a theory.”
