Sites like hubpages will never move up as long as panda is active.The kind of content on their site is total crap. And a huge percentage of it is scraped. But if they move up leaving others behind, only god can save google.
The mere size of those sites makes recovery even more problematic. I think the probability of recovery may increase with decreasing site size. Smaller sites are easier to clean up, and will probably represent a larger fraction of depandilization...assuming they are/become valuable (e.g., not a "farm"), and many may have been borderline from the beginning.
