Google Testing Organic Results In Paid?

Several people noticed this apparent experiment Google is running where some organic content (such as video or product listings) is showing up on the right-hand side of the results page, right amongst the paid listings. Only time will tell if this experiment succeeds and they end up making this move permanent. However, if they do it will dovetail interestingly with the change they recently made to how top paid placements (above organic listings on the left) are awarded and charged. If organic content is moving paid listings down, then those spots will become even more valuable.
