This algo rollout has illustrated with no doubt the victory of a specific spam technique, which I shall refer to as "Multiple Domains Spam".
For example we see a niche related to "Assisted Living" where there are few, large, national 'referral' sites who are buying up domains, and 'leasing' others, so more and more they take up a good number of the top 10 Google Serps.
I read on twitter about another example of "Multiple Domains Spam". A person is spamming Google through several domains. He changes the domain frequently once Google penalises the current domain.
I don't think Panda and Penguin have been able to deal with that kind of spam. Furthermore I see "Multiple Domains Spam" has emerged victorious through the current rollout.
Finaly I wish to mention that I have noticed on twitter that Matt Cutts has already been informed about above mentioned cases of spam in details.
