Vita 'UMD Passport' won't be offered in US

It will not be possible to get discounted Vita downloads of the disc-based UMD games you bought for PSP in the US. A Sony representative told Kotaku that the "UMD Passport" service will not be available to American Vita owners.

Of course, you'll still be able to buy any digitally-distributed PSP games through the Vita's PlayStation Store and play them on the new hardware — and you'll be able to play the PSN games you already bought on your PSP. But those UMD games will be of no use unless you keep your PSP.
