It had a good run, but Sony has decided to bring the curtain down on the PlayStation Portable. The company has announced that June's shipment of the hardware will be the last in Japan, and local users looking to upgrade to the PS Vita can earn a $30 or $40 trade-in discount across the summer. The Verge is reporting that the handheld was quietly discontinued in North America back in January, and we'd assume that European sales of the ten-tear-old device will be next to face the chop. It looks as if Sony is now doing its best to push buyers toward the newly-resurgent PS Vita, which has ridden a wave of success kickstarted by indie titles like Hotline Miami.
