Lordolean,
Agree only GNS and WFL might survive.
WFL has ~$120m debt (by 31/12/2008) with $66m revenue, much better than FEA's ~$200m debt with $23m revenue.
But WFL's $120m debt is also as 3-times big as its total market cap of $33m. The chance for it to survive would also be slim.
Thus GNS looks like the only one to last.
