The N->Infinity limit is proven to be equivalent to the Schroedinger-Newton model, which, though sharing localization properties with the N=2 model, cannot produce decoherence.The statement about the finite character of the field theoretic version of the model is more transparentGeneral Relativity and Quantum Cosmologytext
