Of course sooner or later commodities will make a comeback but I can't see it happening soon. Almost every economy worldwide has become dependent on some sort of government stimulus or deficit. Even the BRIC nations have had to resort to relief. Brazil was the latest to lower bank reserves coupled with tax relief for its citizens.
We're a long way off before the world gets its act together.
Good Luck
