More likely this has to do with repackaging the device for what it will be the next few years. the PS Vita is now a PlayStation Now and PS4 streaming device. This likely will be what the box states as it's main purpose in addition to playing Vita games. With PlayStation Now hitting open beta THIS month it makes a lot of sense. All the old inventory has been cleared out and now they can focus on the above mentioned.
