More leading stringers appear to have abandoned String Theory for interesting ideas. First there was Verlinde and now, as mentioned by Resonaances, there is a classicalisation paper by Dvali et al. I have not read it, but I just enjoyed a very nice talk by one of the authors, Cesar Gomez, starting with a heuristic discussion of minimal lengths, generalised uncertainty principles and a UV/IR correspondence.
He briefly mentions deeper holographic principles, underlying their basic idea of automatic creation of classical black hole states in the localisation of energy as a fairy free unitarisation mechanism. Question time included a lovely comment on the quantum classical transition as a domain for mass quantum number generation, which Nature now tells us should centre on neutral particles.
