Penrose's gravity induced collapse has as good a chance as
Bruno's,
At least Penrose has drawn a line in the sand, which can be
experimentally refuted. Though I don't see any motivation for any
collapse base theory since Everett provided an account of
collapse without having to assume it. (Again this is like adding
appending motive demon theory, which is entirely superfluous and
adds whose sole motivation is to preserve the notion of collapse
as physically real rather than apparent)
and a better chance of predicting some surprising but true
physics. Some version of transactional QM also has a chance.
Transactional QM is another complication of the theory, proposing
things we have no evidence for to explain things which have
already been explained from a much simpler theory.
You only think it's simpler because you close your eyes to the
last step in going from a FAPP diagonal reduced density matrix to
an actually diagonal reduced density matrix. A step that is
perfectly equivalent to Bohr and Heisenberg's collapse postulate,
except it tells you where to hide the collapse.
Is the appearance of collapse not describable from the other postulates?
"Appearance" is a psychological concept. So to decide what that means
requires a theory of mind. Most advocates of MWI want to say that
getting the off-diagonal terms of the reduced density matrix "small
enough" is enough to make it "appear" that the wf has collapsed. But
aside from this fuzziness there is the problem that in some other basis
the cross-terms may not be small at all; hence the preferred basis
problem? Do our minds impose a preferred basis? and why should
different minds agree on it?
