PV panel prices stabilizing?

As I have repeated a few times, PV panel prices cannot keep falling. It seems there is evidence that prices have started to go up.  Below is a graph from a blog article from Nigel Morris at this site. The $0.70/Wp price point seems to have been restored. Its early days, earlier than I would have expected, but may indicate that enough of the excess capacity has been worked off to where the big players can exert some control on prices.

Update 03/07/2013 Another report showing PV panel and cell prices stabilizing, this one showing $0.60/W in China.  http://www.enfsolar.com/news/Chinese-Panel-Manufacturers-%E2%80%93-1.6GWp-of-2012-Stock-Unsold
