The last Panda update Version 3.9 was on July 25, almost 1 month ago. Panda updates are now a stabilized affair and usually rolls out on monthly basis. So, any webmaster who has taken appropriate steps to remove or corrected low quality, or duplicate content gets a chance to recover from Google Panda every month.
Contrary to Panda, the Penguin updates are not so stable and affecting lots of sites, due to addition of more and more signals to fight web-spam. May be in the future, after removing a significant amount of spammy links from the web, we can expect Penguin algorithm on a regular, or monthly basis.
