I don’t know if the leak is on purpose. It shows a Cantonese speaking Google Engineer demonstrating Google Search. Google Search is not new. However, I guess Google Search in Cantonese is something new. Kudos to those with eagle eyes, they have spotted that the engineer is using Android Gingerbread (Android 2.3) that is slated to be released soon.
The original video was pull off from Youtube. However, Engadget managed to upload one to Viddler.
Notice the icon on main page is different from Froyo in this video?
