i dont think there would be a definite time for the crisis to end.
even if the US /obama has taken much of the necessary things to lessen the crisis..still it would take time for the world to respond for the changes..and honestly even if a lot of the big countries has adjusted to the crisis..a lot of the third world countries would not neccessarily be affected.unless the giant countries could forgive the debts of the third world.lol.which is i believe hard to imagine would happen.
