Reuters is reporting today that it is expecting 2013 to be war between Google and Amazon.

Amazon CEO Jeff Bezos got word of a project to scan and digitise product catalogues by Google a decade ago, and the seeds of a rivalry were planted. Bezos was an early investor in Google but he now realised Google had other plans and could encroach upon his online retail experience.

Move forward to 2013 and with both companies spanning online advertising, and retail to mobile gadgets and cloud computing, the big clash is about to happen. It could mark the end of any Google cooperation. Interesting times ahead.
