“[T]he view that the ultimate theory... should be more in accord with the fundamental principles of quantum theory need not imply that such a theory will be any form of quantum theory currently known, such as quantum mechanics or quantum field theory. ...[These] are far from complete or free of deficiencies even within their proper scope. Some new or perhaps now unimaginable theories and very likely new principles may be required to approach the ultimate constitution of nature. Will these theories retain the locality principle? My Bayesian bet would be that this will more likely than not to be the case, but one cannot be certain.”
