The over optimization penalty has been there for at least 5 or 6 years. It primarily targets sites using keyword stuffing in content, HTML title tags, heading tags, hidden text and alt attributes. It is funny that Matt Cutts denied it in 2009, but I remember him talking about it prior to that. In the 2009 video, he primarily focused on PageRank sculpting--which was always a bad idea--and did say that hidden text and other issues were a problem.
That sounds like the Google denial that penalties exist (a few years ago) and was then referring to them as filters, but they do refer to Panda rank demotions and the above-the-fold ad issue as penalties.
I suspect they will also be going after sites the bold keywords repeatedly throughout the text and other cheesy tactics that make it obvious the the page is SEO'd.
Just focus on a topic and write original content and your pages should never get hit with a penalty.
