Sony of America will not be carrying the UMD Passport program that let Japanese gamers transfer their PSP collection to Vita.
The UMD Passport allowed Japanese gamers to insert UMD games into their PSP to register it with their PSN accounts, and then download applicable titles to Vita for a small additional fee.
But Sony US has told Kotaku that it will provide the service for US Vita owners when the console launches on February 22, but offered no reason for its decision. It's also unclear what SCEE's plans are for Europe, but it's not looking good.
As it stands, then, Western gamers will have to repurchase any PSP games they own via PSN - hundreds of which are available digitally - if they wish to see them on Vita's new 5 inch screen.
