Does Colin Bruce have the answer to the size of the multiverse?

I bought his book "Schrodinger's Rabbits" yesterday, and have been
skipping around through it. Some of you may recall that I have
questioned if there is any theoretical way we could estimate the size of
the multiverse if it is not a continuum. I had suggested the size may
be related to the number of possible alternative outcomes down to the
Planck scale (which seemed logical enough to me anyway).

Bruce introduces what I considered a very interesting concept, which may
be old news given the book came out last year, but I do not recall
seeing it discussed. He suggests the holographic principle may provide
the answer. If the amount of information a region of space can contain
is proportional to surface area, might the "volume" contain
subinformation of multiverse processes? To quote Bruce: "Perhaps a cube
10^100 Planck units on a side can indeed store about 10^300 bits of
subinformation or multiverse information, but this capacity has to be
divided between 10^100 world processes, giving only 10^200 bits of
stable "real" information capacity to each."

Bruce admits this is a speculative idea, but provides explanations as to
how it is an interpretation that explains several aspects of our
universe. I will go into more detail about this if anyone cares to hear.

I must admit I'm biased here toward liking the idea because this
directly addresses several key questions I have had about the structure
of the multiverse, including the relevance of the holographic principle
to the MWI. Anyone care to weigh in on the prospects for Bruce's idea?
