Is this Ice Cream Sandwich?

According to an Engadget tipster, a person bought a Nexus S on eBay only to have an OS he didn't recognize on the phone. From the looks of it it looks like this might be the coveted Ice Cream Sandwich. There is no way to confirm this is ICS, but it looks pretty convincing to me. What looks like a nice fusion of Honeycomb and Gingerbread, the latest version of Android will soon be upon us.
