Reports surrounding this policy first appeared online over the weeked on popular gaming forum NeoGAF. The information originated from a Japanese hands-on event Sony held to promote the upcoming public release of the PS Vita, which is scheduled for December 17th.
Unlike the PS Vita, the PlayStation Portable does not require a factory reset in order to take advantage of a second PSN account.
