We still have a few weeks before the official launch of the PlayStation Vita but on the newly announced Sony Entertainment Network, the PSN was absorbed and changed into this. Games like Super Stardust HD and Hot Shots Golf are already available for purchase on the PSN with a discount.
In other Vita related news in Japan Sony announced that PSP owners can repurchase the games in their library through the PSN for a discounted price. Sony later announced that they will not be bringing this over to America. The Vita is available in the first edition bundle on the 15th of the month and then the 22nd for everyone else.
