Aha, I see.
So you do not share EY’s view that MWI is “correct” then and the only problem it faces is recovering the Born Rule?
I agree that obviously what will end up working will depend on what the foundations are :)
I remember that paper by Buosso and Susskind, I even remember sending a mail to Susskind about it, while at the same time asking him about his opinion of ‘t Hoofts work.
If I remember correctly the paper was discussed at some length over at physicsforums.com (can’t remember the post) and it seemed that the consensus was that the authors have misinterpreted decoherence in some way.
I don’t remember the details, but the fact that the paper itself has not been mentioned or cited in any article I have read since then indicates to me that there has had to have been some serious error in it.
Also Susskinds answer regarding ’t Hoofts work was illuminating. To paraphrase he said he felt that ’t Hooft might be correct, but due to there not being any predictions it was hard to hold a strong opinion either way on the matter. So it seems Susskind was not very sold on his own idea.

Gerard ‘t Hooft actually does rely on what people call “superdeterminism”, which I just call “full determinism”, which I think is also a term ’t Hooft likes more. At least that is what his papers indicate. He discuss this some in a article from 2008 in response to Simon Kochen and John Conway’s Free Will Theorem. You might want to read the article: http://www.sciencenews.org/view/generic/id/35391/title/Math_Trek__Do_subatomic_particles_have_free_will%3F After that you might want to head on over to arxiv, ’t Hooft has published a 3 papers the last 6 months on this issue and he seem more and more certain of it. He also adress the objections in some notes in those papers. Link: http://arxiv.org/find/quant-ph/1/au:+Hooft_G/0/1/0/all/0/1
