Is This Retail Payment Data Breach A Trend?

Police near Canton, N.Y., are investigating a payment card data breach at a local retail chain that sounds oddly similar to the Hannaford and other related recent breaches. Is this a coincidence or a gang focused on retail data?

The new information on the Canton WiseBuys breach has the data being grabbed during a system changeover between December 5 and December 20, 2007, according to this WWNYTV story.
