On Friday 10/7, Google registered three domains that seem not related to existing projects.
Google registered GoogleBargain.com on Friday. Google currently offers local bargains in a number of US cities, a program called Google Offers, and they acquired the German site DailyDeal.
They also registered GoogleKnockout.com and GoogleVendor.com/net/org.
Should be interesting to see what these domains are used for in the future.
