With everyone and their mother predicting $580 as the support, I'm not sure that's the best level.
IMHO a better support point is 540-550.
Would love to see it go to sleep for a few years. Don't think we will be that lucky, but G8 meeting undoubtedly will focus on global financial stability. If a US & emerging market bear equity market is what is required to cool down the global economy and restore faith in currencies, so be it. I don't think the CB's will have any objection, particularly now that speculation on hards is sending quite a bit more wealth towards 3rd world economies - more than I think is desired.
Central planners will take these considerations into play and try to control these factors as best they can. The big question on everyone's mind is - can they be controlled?
I, for one, have absolutely no idea.
