"Transactional sales refer to PlayStation Store sales through the PSN/SEN Wallet. Our last quarter (July - September 2012) was our 'biggest' on a global basis with regard to revenue."
So, PSN is apparently on the up, with Sony claiming 97 percent customer satisfaction for the service along with 93 percent renewal intent. The company says the success of PlayStation Plus is driving PSN sales.
Having been around for over two years, PlayStation Plus membership sales almost doubled this summer following the announcement of the Instant Game Collection. Sony is still keeping quiet about specific subscriber numbers, but it sounds like PS Plus is proving to be a significant addition to the PlayStation arsenal.
