Personally I don't think so. I like ex Google employee Vanessa Fox's message:
remember that Panda is a site-wide assessment (so even high quality pages will be impacted)
I'd like to extend that thought to core quality keywords as well, which i think are throttled in some cases.
So although Google has returned traffic, it's only step 1 of a long road to winning sufficient quality and continual enhancement across a site to allow the core terms to rank again. Much more work is required for some sites - and remember it's not just about written unique content, it's about creating valuable differentials in experience.
Some sites can go well beyond their pre Panda traffic and quality if they get it right. Although beating brands on core terms looks a lot tougher.
