Judging from the Techcrunch leak at the start of the month(http://techcrunch.com/2013/03/04/google-is-building-a-same-day-amazon-prime-competitor-google-shopping-express/ http://techcrunch.com/2013/03/04/google-is-building-a-same-d...) this product belongs to the new Advertising & Commerce unit which was formed when the Maps and Commerce unit was broken up this month. A product maintained by Google's dedicated monetization unit probably has a better chance of being somewhat stable.
