I've been following those sales addresses previously discussed for some time now, and they do all funnel into maybe 20-30 addresses that seem to be contained within maybe 5-6 wallets.  You can tell from things like key sweeps that wallets are clustered, and from the central "node" addresses (like 13p5iQkqBEVgKmPeJqEL2LBRS44PjX1dZL), a number of txs with nice, round amounts get shuffled through and around to new smaller addresses, but occasionally lump to quite large sums. 

If these are indeed friedcat/AM's wallets, then damn, he shuffles the funds often and holy hell, AM has a lot of BTC on the books right now.  Granted, nothing's appearing in the self-mining addy or in the shareholder payout.  And again, I don't expect a large part of what's on the books to be paid out as divs (divs were way, way too large last time, imo).
