Backtracking on comments it made earlier this month, Sony is now saying the PlayStation Vita will allow only one PSN account per unit.

Wired first reported that Sony said users could switch memory cards in order to use multiple PSN account IDs on a Vita handheld. Now that doesn't appear to be the case.

“[The] PSN account is tied to the hardware and the memory card, not just the card,” a Sony representative told Wired, “which means that if a second person is using your Vita, it’s not just a case of switching out memory cards, it’s clearing out all of your saved data on the Vita itself when you do the factory reset.”

“In other words, PlayStation Vita is intended to be played by only one user." Game Informer followed up with Sony for additional clarification and received the following statement:

"Like PSP, PS Vita is intended to be played by only one user as a personal portable entertainment system," SCEA said. "As such, the spec is set so that only one PSN account will be connected to one PS Vita hardware."

PlayStation Vita releases on February 22 in North America, Australia, Latin America and Europe. it hits Japan this Saturday.
