Have you incorporated the
Ron-Shamir Entities into this? The paper's a little dated and it's unclear whether the balances on pg. 11 are still accurate, but it'd mean at least two additional billionaires (Entities A and C).
Their credibility is in question since they recently published the poorly-formed and dubious study positing Satoshi and DPR are perhaps either the same or at least linked personally (
http://bits.blogs.nytimes.com/2013/11/23/study-suggests-link-between-dread-pirate-roberts-and-satoshi-nakamoto/), a study which was
funded by the Citi Foundation. Citigroup, of course, being the first of the major banks to fire the first "real" shot into the realm of upstart currency and bank circumvention, in the coming cold war on cryptocurrency-fiat transfers (

Hopefully it stays below the main consciousness, but the damage has been done because it is out there, and all you have to do is inadvertently search for DPR or SR and find it on the first page of google.
They have already retracted that aspect of their findings, too:
