ehh, don't hold your breath to get back. There are reports of only a few recoveries... and mostly people grumbling about staying hit. We've been suffering since Feb. 24th despite spending thousands of dollars in dev/design/content etc. over the year.
Wish you the best... so I'll give you this advice: "Don't hold your breath... and don't feel bad about not recovering... there doesn't seem to be a "quick fix" with Panda"
