Ignoring the complete lack of progress here, if I understand the liquidators report correctly:

1.  Gox is holding about $51 million and change in assets from Bitcoinica

2.  The total of all claims amounts to a measly $1.5 million

I'm assuming the $1.5 million number presumes a bitcoin valuation of $11 a piece. 

If legal action is taken, and the funds are reclaimed, then after the $1.5 million is repaid the remaining $49.5 million windfall (minus liquidator and legal costs) goes to Ator / Wendon Group?

If that's the case, the unsecured creditors have little incentive to pitch in when the liquidator decides to pass the hat to come up with money for lawyers.  Seems like Ator/Wendon has the most to gain from this, so I can't imagine anyone else footing the bill for it.  Unless of course they decide to pay back BTC claims at something closer to today's exchange rate, in which case the situation probably changes significantly.

Regardless, seems like $51 million in assets vs. $1.5 million in liabilities leaves enough room to launch a whole fleet of lawyers to Japan.
