If the Fed raises rates this week, it may well do so. If the Fed backs off, it'll be the signal that they cannot protect the economy and the $US at the same time. The $US will tank, and Gold will pass $410.
I think that Gold is a lot easier to predict long-term, though. I think that "we" really want and need the $US to be trashed, and that will eventually happen. So I'm seeing Gold passing $1000 in the next seven years, and the miners quadrupling.
Given that the Market won't be going much of anywhere (as in 1973-1983), Gold will be the outstanding investment during that period.
