Actually, the link shows a prediction of a 14.7% DECLINE from June 2009 to June 2010, followed by a 11.8% Gain from June 2010 to June 2011.

So the title to this thread is at the very least misleading.

Since prices are up a few percent since June 2009 to now, they are implying a ~17% decline over the next 9 months.
